of course it works, you can still catch covid, as I've posted on here many times it will stop the vast amount of people dying thou.
Big Pharma Fred, a $1 a day, an Astra Zeneca vaccine only cost the UK gov about $3 a shot, that's cost the gov\tax payer $6 for the 2 shots since March when I had the first one , so $6 usd or 6 * $30 = $180 usd
