Extending the time between vaccines.
Jump to: Newest in thread
Based on what was said today, then I’d say yes.... vaccinate more quicker, give the base protection and then top up when next batch is ready. This should hopefully relieve some of the pressure the nhs are dealing with and hopefully reduce the number of deaths and serious infections.
Scientist words today:-
“A first dose of the jab gives around 70% effectiveness from three weeks after immunisation.
However, he said it was 80% effective when there was a three-month interval between the first and second doses”
So base measures still needed, masks, SD etc to protect yourself and others. You won’t know if it’s been effective until you catch the virus, but it’s a step in the right direction. |

It may seem logical to do that and spread the time between doses to vaccinate more folk more quickly.
The Oxford / Astra Zenica vaccine is the one to do that as the makers already are saying some degree of immunity is created from and single dose but you still need 2 for maximum chance of immunity. Plus its only costing £3 a dose.
However Pfizer have said there are no guarantees their jab will work properly or even at all if the doses are given 12 weeks apart (as the news claims the Govt is considering). At $37 (approx £27) a dose it could be an expensive mistake if it means it doesn't work).

"What i heard todsy they not even sure if it going work
They dont even answer bloody questions
One guy asked everyone a good question and all they did was not answer"
Yes it's crazy but they are some very informed fabbites who make a lot of sense and can be fact checked. |

As I understand it Pfizer rigorously kept to a 3 week schedule (which would have been chosen based on previous 2 dose vaccine strategies) and they simply don't have any data on any other time interval so can't make any promises. However there's little reason to believe that a 12 week interval would make a big difference to its effectiveness. Indeed I believe that some well informed people are pushing for a single dose strategy at the moment as it is thought the first dose gives the bulk of immunity so giving 2 people 1 dose each is more efficient than 1 person 2 doses.

Politicians are trained not to answer questions incase it causes problems or sets policy and scientists are trained to give the correct answer which is usually complicated and covered with caveats, and that's when they have an answer.

"As I pointed out on a thread of a similar nature.....
Tony Blair said this and was vilified for it (give everyone one dose BEFORE the second, to give some form of protection)."
I did do a search before i posted.

The Cambridge (AstraZeneca) vaccine will likely replace the Pfizer version fairly quickly and they say that the second dose should be at least 3 weeks and no more than 12 weeks... this fits with the proposed three month timeliness reasonably well.

The problem is the Pfizer vaccine is hard to store must be delivered after three weeks of first use so fo mass vaccination of millions is impracticle.
Also expensive.
Astro is easy to store,transport and more flexibility on second dose.
Also cheaper and manufactured in the UK it is a no brainer even for Hancock
