Samtliga rapporter som kommit från Israel, Skotland och nu UK visar att det tar mer än 30 dagar innan man byggt upp tillräcklig ("tillräcklig" kanske är fel ord, "maximal" är möjligen ordet jag letar efter) immunitet. Intressant att det tar så lång tid.
En dos av Pfizer's eller AZ-vaccinet skyddar bra enl. ny studie i UK. Andra dosen av Pfizer's ger ytterligare skydd. Data saknas för AZ-vaccinet då man inte har kommit igång med andradosen där:

Covid: France approves AstraZeneca vaccine for over-65s
New data show vaccines reduce severe COVID-19 in older adults
New data show both Pfizer-BioNTech and Oxford-AstraZeneca vaccines significantly reduce severe COVID-19 in older adults.
Today Public Health England (PHE) has submitted a pre-print of a real-world study that shows that both the Pfizer and Oxford-AstraZeneca vaccines are highly effective in reducing COVID-19 infections among older people aged 70 years and over. Since January, protection against symptomatic COVID, 4 weeks after the first dose, ranged between 57 and 61% for one dose of Pfizer and between 60 and 73% for the Oxford-AstraZeneca vaccine.https://www.gov.uk/government/news/new-data-show-vaccines-reduce-severe-covid-19-in-older-adults
The pre-print article:
compares the rate of vaccination in symptomatic people aged over 70 years of age who test positive for COVID-19, compared to those who test negativeIn the over 80s, data suggest that a single dose of either vaccine is more than 80% effective at preventing hospitalisation, around 3 to 4 weeks after the jab. There is also evidence for the Pfizer vaccine, which suggests it leads to an 83% reduction in deaths from COVID-19.
compares the rate of hospitalisation in confirmed COVID-19 cases aged over 80 who were vaccinated more than 14 days before testing positive, compared to unvaccinated cases
compares the rate of deaths in confirmed COVID-19 cases aged over 80 who were vaccinated with Pfizer vaccine more than 14 days before testing positive, compared to unvaccinated cases
The data also shows symptomatic infections in over 70s decreasing from around 3 weeks after one dose of both vaccines.

Covid: France approves AstraZeneca vaccine for over-65s
The French government says older people with pre-existing conditions can now get AstraZeneca's Covid-19 vaccine, revising its stance on the issue.https://www.bbc.com/news/world-europe-56242617
"People affected by co-morbidities can be vaccinated with AstraZeneca, including those aged between 65 and 74," the health minister said.
