From the BBC:
The Seychelles, which has fully vaccinated over 60% of its population against Covid-19, is bringing back restrictions amid a rise in cases.
The archipelago of nearly 100,000 people recorded close to 500 new cases in the three days to 1 May and has about 1,000 active cases.
A third of the active cases involved people who had had two vaccine doses, the country's news agency said.
The rest had either had a single dose or were unvaccinated.
Hmmmmm.....
Apparently the vaccine made by the Chinese company Sinovac isn't very effective against the China Virus, so maybe that's the reason?
Chile has had a similar experience after vaccinating most of it's adult population with the Sinovac vaccine, and has reintroduced lockdown measures after covid cases rose again.
We'll be fine. If you survive the AZ vaccine, you'll be unstoppable!
