Are COVID-19 vaccine boosters the way ahead?

As national agencies such as the CDCTrusted Source note, existing data indicate that most COVID-19 vaccines produce a strong immune response that offers sufficient protection against the SARS-CoV-2 virus.However, it remains unclear for how long COVID-19 vaccines — in the current dosages — continue to offer protection.

Nevertheless, booster doses might benefit older individuals or those with a weak immune system, as their bodies may not have generated a strong enough immune response after the initial vaccines.

“Based on current data, for people who respond well to the vaccine, it looks like immunity remains strong for over 12 months and works even against the new variants, My personal opinion is, therefore, that we don’t need to be too worried about boosting them yet,”Dr. Richard Stanton,a reader in the Division of Infection and Immunity at Cardiff University.
