Comparative effectiveness of bivalent BA.4-5 and BA.1 mRNA booster vaccines among adults aged ≥50 years in Nordic countries: nationwide cohort study

Objective To estimate the effectiveness of the bivalent mRNA booster vaccines containing the original SARS-CoV-2 and omicron BA.4-5 or BA.1 subvariants as the fourth dose against severe covid-19.

Design Nationwide cohort analyses, using target trial emulation.

Setting Denmark, Finland, Norway, and Sweden, from 1 July 2022 to 10 April 2023.

Participants People aged ≥50 years who had received at least three doses of covid-19 vaccine (that is, a primary course and a first booster).

Main outcome measures The Kaplan-Meier estimator was used to compare the risk of hospital admission and death related to covid-19 in people who received a bivalent Comirnaty (Pfizer-BioNTech) or Spikevax (Moderna) BA.4-5 or BA.1 mRNA booster vaccine as a fourth dose (second booster) with three dose (first booster) vaccinated people and between four dose vaccinated people.

Results A total of 1 634 199 people receiving bivalent BA.4-5 fourth dose booster and 1 042 124 ....

Safety of BA.4-5 or BA.1 bivalent mRNA booster vaccines: nationwide cohort study

Objective To examine the association between the omicron adapted bivalent mRNA covid-19 booster vaccines received as a fourth dose and risk of adverse events.

Design Nationwide cohort study.

Setting Denmark.

Participants 2 225 567 adults aged ≥50 years who received three covid-19 vaccine doses during the study period, 1 January 2021 to 10 December 2022.

Main outcome measures The main outcome measure was rates of hospital visits for 27 different adverse events in a 28 day main risk period after vaccination with a bivalent omicron adapted mRNA booster vaccine as a fourth dose compared with reference period rates from day 29 after the third or fourth vaccine dose and onward.

Results 1 740 417 adults (mean age 67.8 years, standard deviation 10.7 years) received a bivalent mRNA vaccine as a fourth dose. Fourth dose vaccination with a bivalent mRNA vaccine was not associated with a statistically significant increased rate of any of the 27 adverse ....
