COVID-19 vaccines made by Pfizer-BioNTech and Moderna produce a strong immune reaction in the body that may protect against the virus for years, according to a new study, write The Independent.

The latest findings add to growing evidence suggesting that many people who have received a messenger RNA (mRNA) vaccine may not need a booster dose – as long as the virus and its variants do not evolve much beyond their current forms.

The peer-reviewed study, published in the science journal Nature, found both vaccines are likely to offer long-lasting protection against Covid-19.
