A first dose provides around 50-65% protection. Good, but not as good as it can be. Herd immunity is going to require at least 80% of the population to be FULLY vaccinated, as in had both doses. You then also have to await immunity to build up, which takes around one month after a second dose.
The vaccine programme, in my opinion, has been a success story thus far but we are still a good few months from achieving any type of herd immunity threshold. Until that happens, and in reality we still don’t even know if this virus succumbs to herd immunity, variants that are more infectious will be a concern.
The improvements in deaths, hospitalisations and case rates are very apparent, but for us to go back to complete normal we need to be in a position to know that community transmission is virtually impossible. The only way for that to happen is for a huge majority of the population to be immune.
As ever, just sit tight. We’re getting there, we truly are, don’t let these little bumps in the road bring you down. Look at the positives, look at the progress, look at how well we’ve learned to fight this in only a few months.
