China’s COVID vaccines have been crucial — now immunity is waning.

[Preprint] Breakthrough SARS-CoV-2 infections in 620,000 U.S. Veterans, February 1, 2021 to August 13, 2021 – “Vaccine protection declined by mid-August 2021, decreasing from 91.9% in March to 53.9%”.

Observational study in Qatar showed the effectiveness of Pfizer vaccine against any SARS-CoV-2 infection dropped to 20% in months 5 through 7 after the second dose, but effectiveness against severe Covid-19 remained high.

Cohort study: Pfizer vaccine effectiveness against any infections declined from 88% during the first month after full vaccination to 47% after 5 months. Vaccine effectiveness against hospital admissions remained high; 87% within 1 month, and 88% at 5 months after full vaccination, with no significant waning.

COVID vaccine immunity is waning — how much does that matter? – “As debates about booster shots heat up, what’s known about the duration of vaccine-based immunity is still evolving”.

COVID vaccine effects wane over time but still prevent death and severe illness.

Perspective | What we actually know about waning immunity.

Another study shows Pfizer mRNA vaccine immunity is reduced over time.
