Senegal expects waste of 400,000 COVID-19 vaccines by year-end: Report

African governments have been calling for more COVID-19 vaccines to help catch up with richer regions, where vaccine rollouts have been humming along for more than a year.

At least 200,000 COVID-19 vaccines have expired in Senegal without being used in the past two months and another 200,000 are set to expire at the end of December because demand is too slow, the head of its immunisation programme said on Monday.

Yet, as the pace of supply has picked up in recent weeks some countries have struggled to keep pace. Logistical problems, the short shelf life of vaccines that arrive from donors, and vaccine hesitancy have all kept doses from reaching arms.

Up to 1 million COVID-19 vaccines expired in Nigeria last month, Reuters revealed.

Frequently Asked Questions

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.

"The main problem is vaccine hesitation," said Ousseynou Badiane, who is in charge of Senegal's vaccine rollout. "The number of cases is decreasing. They ask: 'why is it important to get vaccinated if the illness is not there now'?"

Senegal has recorded more than 74,000 COVID-19 infections and 1,886 deaths, far below the numbers seen in many nations hit harder by the virus. The pace of infection has dropped off since a third wave in July spurred a spike in vaccine demand. The country occasionally records no new daily cases.

But apathy hurts the vaccination drive. Senegal has administered nearly 2 million doses of vaccines so far, Reuters data shows, enough to fully vaccinate only about 5.9% of the population.

It is currently vaccinating between 1,000 and 2,000 people per day, Badiane told Reuters, down from 15,000 during the summer. At this pace, it cannot use all the vaccines it has.

"We are not optimistic" about using the other 200,000 doses before they expire at the end of the month, he said. "We don't expect any demand increase before then."

He did not specify the make of the vaccines.

Part of the problem is the short shelf life of vaccines that arrive from donors that include the United States and China. Senegal refuses to take vaccines with a shelf life shorter than three months, but even that creates difficulties.

Badiane hopes the government can introduce some kind of restrictions on the unvaccinated to drive up inoculation rates, including the use of a health pass as many other countries have done.

"Without the restriction, the population will not get vaccinated," he said.
