Combination of infections and vaccinations,

enough community protection that we’re not going to see a repeat of what we saw last year at this time

Re bivalent effectiveness

It is clear now, despite an initial bit of confusion

United States

Nearly $5 billion to buy 171 million bivalent boosters

(Pfizer BioNTech, Moderna)

Hobson’s choice

Dr. Ashish K. Jha, White House’s Covid-19 response coordinator

Still heavily promoting vaccination

Nothing I have seen in the subvariants makes me believe that we can’t manage our way through it effectively, especially if people step up and get their vaccine

So far, 35 million people, (11% of over 5s) one bivalent shot

Effectiveness of Bivalent mRNA Vaccines in Preventing Symptomatic SARS-CoV-2 Infection — Increasing Community Access to Testing Program, United States, September–November 2022

This is the clinical trial, previous work had only been based on antibodies

Benefits are mentioned, adverse reactions are not

Systemic symptoms

Fatigue (30.0%–53.1%)

Headache (19.7%–42.8%)

Myalgia (20.3%–41.3%)

Fever (10.2%–26.3%)

Reported inability to complete normal daily activities

10.6% among aged over 65 years

19.8% among aged 18–49 years

Bivalent boosters provided significant additional protection against symptomatic SARS-CoV-2 infection

Relative vaccine effectiveness (rVE) of a bivalent booster dose,

compared with that of more than 2 monovalent vaccine doses,

30% and 56% aged 18–49

with relative benefits increasing with time since receipt of the most recent monovalent vaccine dose.

Staying up to date with COVID-19 vaccination, including getting a bivalent booster dose when eligible, is critical to maximizing protection against COVID-19
