These results are consistent with data from COV-BOOST, which showed that the Pfizer BioNTech vaccine was well-tolerated as a third-dose and provided a strong boost response.
A half-dose of Moderna vaccine might be available. For those who have received the Moderna vaccine previously, mRNA vaccines may not be available.
Professor Wei Shen Lim is the Chair of COVID-19 Immunization for the JCVI. He stated: “The UK’s COVID-19 vaccine programme has been enormously successful in protecting people from hospitalization and death. The main purpose of the booster program is to extend that protection and decrease serious disease as the weather gets colder.
The JCVI recommends that a booster be given to those most at risk to maximize protection against an unpredicted winter. These people are likely to be eligible for an annual flu vaccine, and we recommend that they take advantage of this opportunity.
