Data suggests reported cases of rare heart inflammation are relatively higher after Moderna's vaccine compared with the Pfizer/BioNTech shots, Canadian health officials said last week.

The U.S. Food and Drug Administration on Monday gave full approval to Moderna Inc's (MRNA.O) COVID-19 vaccine for people age 18 and older, making it the second fully approved vaccine for the virus.
The Moderna vaccine has been authorized for emergency use in the United States since December 2020, and will now be sold under the brand name Spikevax. Pfizer (PFE.N) and BioNTech's COVID-19 shot using similar technology received full approval in the United States last year for people aged 16 and older after also first gaining emergency authorization.

"The public can be assured that Spikevax meets the FDA’s high standards for safety, effectiveness and manufacturing quality required of any vaccine approved for use in the United States," Acting FDA Commissioner Dr. Janet Woodcock said in a statement.

Moderna's vaccine is cleared for use in more than 70 countries, including Canada and the European Union.

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.
