Latest cohort studies from Scotland, released in early March this year, using the entire Scottish population of 5.4M people, also a double blind study with 1.2M vaccinated and 1.2M unvaccinated people.
Both COVID-19 vaccines, 50/50 Pfizer and AstraZeneca, reduced severe infections by 85% on average just 7 days after receiving the vaccines, and reduced hospital admissions by 90%.
At 28 days Pfizer exhibited 85% efficacy, AstraZeneca exhibited 92% efficacy. This is predicted based on how the various vaccines work, antibody which is short term or Memory T-Cell which is long term.
Even better news, both vaccines have been shown to also inhibit transmission in populations older than 65 years, by between 40% and 70%.
