In this emerald isle, people take to any form of vaccination, like the legendary ducks take to water. Offer them a vaccine against anything and they will take it; at least most of them would do so. The vaccine antagonists and anti-vaxxers are extremely few and far between, so as to be almost a virtual non-entity. With a very high literacy rate, and a population that is prepared to take heed to the hilt, the axiom that dictates ‘prevention is better than cure’, it is the absolute dream of the experts in the public health scenario that there is unmitigated abiding interest on the part of our populace to get vaccinated against COVID-19. It has been said that vaccines do not save lives but vaccination most definitely does. Vaccines have to be given to people for them to produce the optimal effects. A receptive population to such a notion is indeed, a much-fancied reverie of all health service providers.

In such a background, it is most laudable that Sri Lanka is going pell-mell, even in an impetuous rush, to vaccinate her population against COVID-19, at what could best be described as at break-neck speed. Even given the spectacle of an insufficiency of adequate stocks of the coronavirus vaccines to freely vaccinate the population, the authorities are making the very best of the situation. We must, of course clearly appreciate the steps taken by the Government and the Ministry of Health in this initiative. The tri-forces, the Army in particular, have to be congratulated, in playing the lead role in organising a scheme of things to administer the vaccines in an orderly fashion. TAKE A BOW; ALL OF YOU, you are indeed giving the very best of yourselves in this endeavour.

Well, the goal is to somehow secure a high enough herd-immunity to defeat the virus; most definitely a commendable final goal. The currently prevalent mantra is to vaccinate, vaccinate, and vaccinate even more. Yet for all that there is much misinformation and an infodemic doing the rounds, especially on social media, about widespread speculations on loss of sexual prowess, impotence, subfertility and infertility, as undesirable effects of the COVID-19 vaccines. THERE IS ABSOLUTELY NO SCIENTIFIC BASIS FOR ANY OF THESE IMPLICATIONS. NONE OF THE CURRENTLY AVAILABLE COVID-19 VACCINES DO ANY OF THIS. It is just stupid covidiocy on the part of a few anti-vaxxers. It has induced a lot of young people to refuse the vaccine. This is a crime against humanity to spread such falsehoods. It is absolutely crucial to realise that the current vaccination drive is just a very important one of quite a few things we can do to try and keep the coronavirus at bay.

We have seen the fantastic results of immunisations against ‘child-killer diseases’ in paediatric healthcare. This author, as a young junior doctor, was witness to the ravages of the much-feared childhood diseases that killed or maimed scores of young children even in the second half of the last century. Those diseases such as tetanus, diphtheria, whooping cough, polio, measles, Japanese encephalitis; just to mention a few that took scores of young lives of yore, are a thing of the past now. Adequate vaccination has completely wiped them out. The last case of childhood polio in Sri Lanka was seen just around a quarter of a century ago. The young junior doctors of today and the current lot of medical students have not seen any of these dreaded diseases.

In the child healthcare scenario, vaccination has become the panacea for all ills in the above-mentioned diseases. In the same vein, it is quite reasonable to expect the coronavirus vaccines to provide a similar end-result. However, is it really so? It is a most lamentable fact that it is perhaps not quite so.

There is a well-recognised fundamental difference between all the vaccines that are used to prevent the much-feared childhood diseases of the past and the currently available vaccines against the coronavirus that is causing the current pandemic. The vaccines against all those childhood diseases COMPLETELY PREVENT children getting the disease!!!, period. Well, if the recipients are protected against getting the infection, it is the end of the story; a definitive conclusion of the matter in hand.

However, right up to just a few days ago, none of the currently available vaccines against COVID-19, were thought to be able to COMPLETELY PREVENT anyone getting the disease to any appreciable degree. How they work is by reducing the severity of the disease and by preventing the deaths. So…, the basic end-result characteristics of all the currently available COVID-19 vaccines were thought to be quite different to the standard vaccines against all other infective diseases. One could still get the disease in spite of being vaccinated against COVID-19 and would still be able to spread the illness to others.

Yet for all this, there seems to be a little bit of light at the end of the tunnel. In a most recent scientific publication in the New England Journal of Medicine, released as recently as 22nd September 2021, an interim analysis of a large study conducted in 99 centres of the USA has shown significant protection against CONTRACTING THE DISEASE as well as AGAINST MORE SEVERE DISEASE AND DEATH by the mRNA-1273 (Moderna/Spikevax) vaccine, administered as two doses 28 days apart. Vaccine efficacy in preventing Covid-19 illness was 93.2%, the effectiveness in preventing severe disease was 98.2% and the efficacy in preventing asymptomatic infection, starting 14 days after the second injection, was 63.0%. Vaccine efficacy was consistent across ethnic and racial groups, age groups, and participants with coexisting conditions. No safety concerns were identified.

Be that as it may, added to all our problems, now there is the daunting spectacle of the various types of variants and mutants, ranging from Alpha through delta, even to Epsilon and most recently to a particularly nasty strain called ‘Mu’, of the coronavirus which could cause problems even in the fully vaccinated. We still do not understand completely the potential impact of these more virulent strains in vaccinated people.

However, a case in point in relationship to these facts is the presently dominant situation in Israel. That country, one of the fastest in vaccination and most-vaccinated nations in the world, in spite of almost the entire population being vaccinated, is having some problems at the present time. By mid-March 2021, Israelis were partying as lockdowns ended and by April, masks had more or less vanished, turning the tiny country into a tantalising glimpse of a post-pandemic future. However, the crafty blight of a coronavirus seems to have come back with a vengeance. From a few dozen daily cases in early June 2021, even zero on June 9, new daily COVID infections twice hovered near 6,000 very recently, the highest daily rate in six months. Having won early access to supplies of the BioNTech/Pfizer jab in exchange for sharing nationwide data on how mass vaccination drives affect the pandemic, Israel is a closely watched indicator of a country where well-inoculated developed economies are heading.

As new infections soared, so did the long tail of hospitalisations in Israel. Even though the unvaccinated were five to six times as likely to end up seriously ill, the vaccine’s protection was waning fastest for the oldest; the most vulnerable, who got their first jabs as early as December 2020. At this rate, health officials predicted at least 5,000 people would need hospital beds by early September, half of them with serious medical needs, twice as many as Israel is equipped to handle. The current Prime Minister of Israel was honest with Israelis when he announced a new measure just a couple of weeks ago, whereby the government was trying to cushion the blow. On August 1, it had started offering people, over 60, a third shot of the Pfizer vaccine, embarking on its own public health experiment as it tumbled into an unpredictable fourth wave. So far, 775,000 people have taken their third shot and doctors say they can see antibody counts rising measurably within days of the third jab.

For Israelis, the booster shots are a reminder that they are still on the frontier of Covid-19 vaccinations. They celebrated when they were the first to get jabbed, cheering Pfizer as lockdowns ended in March 2021. Now, they are the first to experience the limits of the vaccine and the first to accept a long-whispered inevitability: the need to give regular booster shots to stay protected.

All these facts tend to bring into sharp focus, again and AGAIN, the undoubted importance of time-tested manoeuvres of avoiding crowds, maintaining a social distance of at least one to two metres, wearing suitable and effective masks; even double-masking, and repeated washing of hands, as our own personal weapons against this dastardly blight. Vaccination against COVID-19 will probably not be the panacea for all ills in combating this pandemic, although it would be a very powerful tool in the hands of the authorities in their quest towards victory over this disease. It will certainly not be the ultimate ‘SILVER BULLET’ against the disease.

If there is a lesson to be learnt from Israel today, it is this: corona, in fact, is not over; perhaps not for quite a while. This summer was just an intermission. Next may come winter., sadly perhaps, a winter of discontent. We do hope to high heaven that it may not be so for this beautiful and much-treasured Motherland of ours.

High govt. revenue and low foreign exchange reserves High foreign exchange reserves and low govt. revenue!

First shipment of vehicles imported to Sir Lank after the lifting the ban on automobile imports

Government has permitted, after several years, the import of motor cars. Imports, including cars, were cut off because the government then wisely prioritised importing other commodities vital to the everyday life of the general public. It is fair to expect that some pent-up demand for motor vehicles has developed. But at what prices? Government seems to have expected that consumers would pay much higher prices than had prevailed earlier.

The rupee price of foreign exchange had risen by about half from Rs.200 per US$ to Rs.300. In those years, the cost of production of cars also had risen. The government dearly wanted more revenue to meet increasing government expenditure. Usually, motor cars are bought by those with higher incomes or larger amounts of wealth. Taxes on the purchase of cars probably promote equity in the distribution of incomes. The collection of tax on motor cars is convenient. What better commodity to tax?

The announced price of a Toyota Camry is about Rs.34 million. Among us, a Camry is usually bought by those with a substantially higher income than the average middle-income earner. It is not a luxury car like a Mercedes Benz 500/ BMW 700i. Yes, there are some Ferrari drivers. When converted into US dollars, the market price of a Camry 2025 in Sri Lankan amounts to about $110,000. The market price of a Camry in US is about $34,000, where it is usually bought by income earners in the middle-middle class: typically assistant professors in state universities or young executives. Who in Lanka will buy a Camry at Rs.34 million or $110,000 a piece?

How did Treasury experts expect high revenue from the import of motor cars? The price of a Toyota Camry in US markets is about $34,000. GDP per person, a rough measure of income per person in US, was about $ 88,000 in 2024. That mythical ‘average person’ in US in 2024, could spend about 2.5 month’s income and buy a Toyota Camry. Income per person, in Lanka in 2024, was about $ 4,000. The market price of a Camry in Lanka is about $ 133,000. A person in Lanka must pay 33 years of annual income to buy a Toyota Camry in 2025.

Whoever imagined that with those incomes and prices, there would be any sales of Camry in Lanka? After making necessary adjustments (mutatis mutandis), Toyota Camry’s example applies to all import dues increases. Higher import duties will yield some additional revenue to government. How much they will yield cannot be answered without much more work. High import duties will deter people from buying imported goods. There will be no large drawdown of foreign exchange; nor will there be additional government revenue: result, high government foreign exchange reserves and low government revenue.

For people to buy cars at such higher prices in 2025, their incomes must rise substantially (unlikely) or they must shift their preferences for motor cars and drop their demand for other goods and services. There is no reason to believe that any of those changes have taken place. In the 2025 budget, government has an ambitious programme of expenditure. For government to implement that programme, they need high government revenue. If the high rates of duties on imports do not yield higher government revenue as hypothesised earlier, government must borrow in the domestic market. The economy is not worthy of raising funds in international capital markets yet.

If government sells large amounts of bonds, the price of all bonds will fall, i.e. interest rates will rise, with two consequences. First, expenditure on interest payments by government will rise for which they would need more revenue. Second, high interest rates may send money to banks rather than to industry. Finding out how these complexities will work out needs careful, methodically satisfactory work. It is probable that if government borrows heavily to pay for budgetary allocations, the fundamental problem arising out of heavy public debt will not be solved.

The congratulatory comments made by the Manager of IMF applied to the recent limited exercise of handling the severity of balance of payments and public debt problems. The fundamental problem of paying back debt can be solved only when the economy grows fast enough (perhaps 7.5 % annually) for several years. Of that growth, perhaps, half (say 4 % points) need to be paid back for many years to reduce the burden of external debt.

Domestic use of additional resources can increase annually by no more than 3.5 percent, even if the economy grows at 7.5 percent per year. Leaders in society, including scholars in the JJB government, university teachers and others must highlight the problems and seek solutions therefor, rather than repeat over and over again accounts of the problem itself.

Growth must not only be fast and sustained but also exports heavy. The reasoning is as follows. This economy is highly import-dependent. One percent growth in the economy required 0.31% percent increase in imports in 2012 and 0. 21 percent increase in 2024. The scarcity of imports cut down the rate of growth of the economy in 2024. Total GDP will not catch up with what it was in (say) 2017, until the ratio of imports to GDP rises above 30 percent.

The availability of imports is a binding constraint on the rate of growth of the economy. An economy that is free to grow will require much more imports (not only cement and structural steel but also intermediate imports of many kinds). I guess that the required ratio will exceed 35 percent. Import capacity is determined by the value of exports reduced by debt repayments to the rest of the world. The most important structural change in the economy is producing exports to provide adequate import capacity. (The constant chatter by IMF and the Treasury officials about another kind of structural change confuses the issue.) An annual 7.5 percent growth in the economy requires import capacity to grow by about 2.6 percent annually.

This economy needs, besides, resources to pay back accumulated foreign debt. If servicing that accumulation requires, takes 4% points of GDP, import capacity needs to grow by (about) 6.6 percent per year, for many years. Import capacity is created when the economy exports to earn foreign exchange and when persons working overseas remit substantial parts of their earnings to persons in Lanka. Both tourism and remittances from overseas have begun to grow robustly. They must continue to flow in persistently.

There are darkening clouds raised by fires in prominent markets for exports from all countries including those poor. This is a form of race to the bottom, which a prominent economist once called ‘a policy to beggar thy neighbour (even across the wide Pacific)’. Unlike the thirty years from 1995, the next 30 years now seem fraught with much danger to processes of growth aided by open international trade. East Asian economies grew phenomenally by selling in booming rich markets, using technology developed in rich countries.

Lanka weighed down with 2,500 years of high culture ignored that reality. The United States of America now is swinging with might and main a wrecking ball to destroy that structure which they had put up, one thought foolishly, with conviction. Among those storms, many container ships would rather be put to port than brave choppy seas. High rates of growth in export earnings seem a bleak prospect. There yet may be some room in the massive economies of China and India.

Consequently, it is fanciful to expect that living conditions will improve rapidly, beginning with the implementation of the 2025 budget. It will be a major achievement if the 2025 budget is fully implemented, as I have argued earlier. Remarkable efforts to cut down on extravagance, waste and the plunder of public funds will help, somewhat; but not enough. IMF or not, there is no way of paying back accumulated debt without running an export surplus sufficient to service debt obligations.

Exports are necessary to permit the economy to pay off accumulated debt and permit some increase in the standard of living. Austerity will be the order of the day for many years to come. It is most unlikely that the next five years will usher in prosperity.

St. Anthony’s Church feast at Kachchativu island

Published

on

Fort Hammenhiel

The famous St. Anthony’s Church feast this year was held on 14 and 15 March. St. Anthony, as per Catholic belief, gives protection and looks after fishermen and seafarers like me. Many Buddhist seafarers are believers in St. Anthony and they usually keep a statue of the saint in their cabins in the ship or craft.

St. Anthony died on 13th June 1231 at age of 35 years, at Padua in Holy Roman Empire and was canonized on 30 May 1232 by Pope Gregory IX.

I was unable to attend last year’s feast as I was away in Pakistan as Sri Lanka’s High Commissioner. I was more than happy to learn that Indians were also attending the feast this year and there would be 4,000 devotees.

I decided to travel to Kankesanturai (KKS) Jaffna by train and stay at my usual resting place, Fort Hammenhiel Resort, a Navy-run boutique hotel, which was once a prison, where JVP leaders, including Rohana Wijeweera were held during the 1971 insurrection. I was fortunate to turn this fort on a tiny islet in Kytes lagoon into a four-star boutique hotel and preserve Wijeweera’s handwriting in 2012, when I was the Commander Northern Naval Area.

I invite you to visit Fort Hammenhiel during your next trip to Jaffna and see Wijeweera’s handwriting.

The train left Colombo Fort Railway Station on time (0530 hrs/14th) and reached KKS at 1410 hrs. I was highly impressed with the cleanliness and quality of railway compartments and toilets. When I sent a photograph of my railway compartment to my son, he texted me asking “Dad, are you in an aircraft or in a train compartment? “

Well done Sri Lanka Railways! Please keep up your good work. No wonder foreign tourists love train rides, including the famous Ella Odyssey.

Travelling on board a train is comfortable, relaxed and stress free! As a frequent traveller on A 9 road to Jaffna, which is stressful due to oncoming heavy vehicles on. This was a new experience and I enjoyed the ride, sitting comfortably and reading a book received from my friend in New York- Senaka Senaviratne—’Hillbilly Elegy’ by US Vice President JD Vance. The book is an international best seller.

My buddy, Commodore (E) Dissanayake (Dissa), a brilliant engineer who built Reverse Osmosis Water Purification Plants for North, North Central and North Western provinces to help prevent chronic kidney disease is the Commodore Superintendent Engineering in the Northern Naval Area. He was waiting at the KKS railway station to receive me.

I enjoyed a cup of tea at Dissa’s chalet at our Northern Naval Command Headquarters in KKS and proceeded to Fort Hammenhiel at Karainagar, a 35-minute drive from KKS.

The acting Commanding Officer of Karainagar Naval Base (SLNS ELARA) Commander Jayawardena (Jaye) was there at Fort Hammenhiel Restaurant to have late lunch with me.

Jaye was a cadet at Naval and Maritime Academy, (NMA) Trincomalee, when I was Commandant in 2006, NMA was under artillery fire from LTTE twice, when those officers were cadets and until we destroyed enemy gun positions, and the army occupied Sampoor south of the Trincomalee harbour. I feel very proud of Jaye, who is a Commander now (equal to Army rank Lieutenant Colonel) and Commanding a very important Naval Base in Jaffna.

The present Navy Commander Vice Admiral Kanchana Banagoda had been in SLNS ELARA a few hours before me and he had left for the Delft Island on an inspection tour.

Commander Jaye was very happy because his Divisional Officer, when he was a cadet, was Vice Admiral Kanchana (then Lieutenant Commander). I had lunch and rested for a few hours before leaving Karainagar in an Inshore Patrol Craft heading to Kachchativu Island by1730 hrs.

The sea was very calm due to inter-monsoon weather and we reached Kachchativu Island by 1845 hrs. Devotees from both Sri Lanka and India had already reached the island. The Catholic Bishop of Sivagangai Diocese, Tamil Nadu India His Eminence Lourdu Anandam and Vicar General of Jaffna Diocese Very Rev Fr. PJ Jabaratnam were already there in Kachchativu together with more than 100 priests and nuns from Sri Lanka and India. It was a solid display of brotherhood of two neighbouring nations united together at this tiny island to worship God. They were joined by 8,000 devotees, with 4,000 from each country).

The church

All logistics—food, fresh water, medical facilities—were provided by the Sri Lanka Navy. Now, this festival has become a major annual amphibious operation for Navy’s Landing Craft fleet, led by SLNS Shakthi (Landing Ship tanks). The Navy establishes a temporary base in a remote island which does not have a drop of drinking water, and provides food and water to 8,000 persons. The event is planned and executed commendably well under Commander Northern Naval Area, Rear Admiral Thusara Karunathilake. The Sri Lankan government allocates Rs 30 million from the annual national budget for this festival, which is now considered a national religious festival.

The Indian devotees enjoy food provided by SLN. They have the highest regard for our Navy. The local devotees are from the Jaffna Diocese, mainly from the Delft Island and helped SLN. Delft Pradeshiya Sabha and AGA Delft Island. A very efficient lady supervised all administrative functions on the Island. Sri Lanka Police established a temporary police station with both male and female officers.

As usual, the Sinhalese devotees came from Negombo, Chilaw, Kurunegala and other areas, bringing food enough for them and their Catholic brothers and sisters from India! Children brought biscuits, milk toffee, kalu dodol and cakes to share with Indian and Jaffna devotees.

In his sermon on 22nd December 2016, when he declared open the new Church built by SLN from financial contributions from Navy officers and sailors, Jaffna Bishop Rt Rev Dr Justin Bernard Ganapragasam said that day “the new Church would be the Church of Reconciliation”.

The church was magnificent at night. Sitting on the beach and looking at the beautiful moon-lit sea, light breeze coming from the North East direction and listening to beautiful hymns sung by devotees praising Saint Anthony, I thanked God and remembered all my friends who patrolled those seas and were no more with us. Their dedication, and bravery out at sea brought lasting peace to our beloved country. But today WHO REMEMBERS THEM?

The rituals continued until midnight. Navy Commander and the Indian Consul General in Jaffna Sai Murali attended the Main Mass.

The following morning (15) the Main Mass was attended by Vice Admiral Kanchana Banagoda and his family. It was a great gesture by the Navy Commander to attend the feast with his family. I had a long discussion with Indian Consul General Jaffna Sai Mulari about frequent incidents of Indian trawlers engaging in bottom trawling in Sri Lankan waters and what we should do as diplomats to bring a lasting solution to this issue, as I was highly impressed with this young Indian diplomat.

The Vicar General of the Jaffna Diocese, my dear friend, Very Rev Father P J Jabarathnam also made an open appeal to all Indian and Sri Lankan fishermen to protect the environment. I was fortunate to attend yet another St. Anthony’s Church feast in Kachchativu.
