Its never been any different. The vaccine reduces transmission and symptoms but doesn’t prevent you “carrying” the virus and infecting others.
Absolutely, 90%. But at some stage we need to adopt a few protocols which balance the need to minimise virus spread with the demands of 'everyday' living and recognise the benefits of the vaccination programme. Holiday in UK peeps. Where in UK haven't you been so far in your life?
For example are we going to continue to require a double vaccinated 'close contact' of someone who a few days later tests PCR positive to self-isolate? For example in the case above, the test and trace direction is that the daughter will need to (and be directed to) self-isolate. What if she'd been also fully vaccinated (+14 days)?
On the issue of 'vaccination' doesn't give full protection, the Warwick Uni modelling suggests that the majority of future deaths will be people who have been fully vaccinated. The deadly maths is reasonably straightforward. Take two individuals one 80, the other a vaccine hesitant 40.
Then multiply their chances of:
Exposure to infection - say 40 year old thrice as likely
Developing infection - 40 year old 10 times as likely (80yo has 90% protection from vaccinatation)
IFR: for the 40yo = 0.1% For the 80yo = 10%
The vaccinated 80yo is 3 times more likely to die of COVID-19 than the unvaccinated 40yo. (NB the vaccine hesitant 40yo can reduce their OR by a factor of 10 by getting vaccinated.
* All figures rough, but the messages are clear.
1) Sadly statistics suggests a few people will die having tested positive for COVID-19 within 28 days, even if they've been fully vaccinated: a few of the 900 who die in UK every summer week.
2) The higher percentage of the population who get vaccinated the less chance there is of either individual catching COVID-19 in the 'first place'.
