Dutch health officials, on March 14 said they suspended the use of AstraZeneca's coronavirus vaccine for two weeks after "possible side effects" had been reported in Denmark and Norway.

Netherland’s move against the use of AstraZeneca came after several other European and Asian nations had reported blood clots following vaccinations.

Austria, Italy, Bulgaria, Romania, Estonia, Lithuania, Luxembourg, Latvia and non-European Union (EU) countries Norway and Iceland have also banned the use of the vaccine as a precaution after similar reports of blood clots, which European drug regulators are still investigating.

Meanwhile, on March 12, Thailand delayed its roll-out of the AstraZeneca vaccine over blood clot fears. It is the first Asian nation to suspend the use of jab over safety concerns.

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.
