JCVI advises use of additional bivalent vaccine for autumn booster campaign
Published advice updated to include an additional bivalent vaccine now approved by the Medicines and Healthcare products Regulatory Agency (MHRA).
Following on from the previous advice on which vaccines should be used in this year’s autumn booster programme, the Joint Committee on Vaccination and Immunisation (JCVI) has updated its published advice to include an additional bivalent vaccine now approved by the Medicines and Healthcare products Regulatory Agency (MHRA).
Studies indicate the Pfizer-BioNTech bivalent vaccine produces a marginally higher immune response against some variants than the Pfizer-BioNTech mRNA Original ‘wild-type’ vaccine. The clinical relevance of these small differences is uncertain
‘Bivalent’ vaccines have been developed by global manufacturers since the emergence and dominance of the Omicron variant. These vaccines are targeted against antigens (substances that induce an immune response) from 2 different COVID-19 strains, or variants.
All of the available booster vaccines offer very good protection against severe illness from COVID-19. As more vaccines continue to be developed, the committee will consider their use in the autumn programme.
Professor Wei Shen Lim, Chair of COVID-19 immunisation on the JCVI, said:
It is very encouraging that more vaccines continue to become available and we now have another option to add to the vaccines already advised for the autumn booster campaign.
Winter is typically the time of greatest threat from respiratory infections. We strongly encourage everyone who is eligible to have their booster vaccine this autumn when it is offered. This is our best defence against becoming severely ill from COVID-19.
