A virus can evolved into different strains, How do Dr's know it work on a new strain of the virus if the vaccine has not been tested against it?

The thought of having alien material pumped into my body or the basis that it MIGHT prevent something is horrible.

The risk of that material (liquid) which may be already contaminated, as I guess they don't test every sample , is far higher than what it is supposed to prevent.

If it was to save a life then that is a different matter as well I know

A human body builds up its own antibodies to prevent the body from getting a lot of illnesses and the flu jab takes that that prevention away .

Just ask your Dr how long it lasts for and you will not get a definate time because they can't. May only work for a couple of days or a few months.

FLU jabs ? steer well clear. I would want to know a hell of a lot more first
Such as =
when was the vaccine made
Is it near the use by date or past it already
what is the "life spam" of the vaccine
how long does it work for in a human body
What checks have been made on that particular batch
How many times has it been handled
How secure was it stored to prevent contamination
What reaction may some bodied have to it
would mine react badly
Does blood type make a difference
would previous illnesses cause concern that it might not work

Those who have the jab should be isolated for 14 days so they don't spread the flu from the tab

Only had the flu vaccine the once in 1972 when I started a new job. Apparently the management paid for all the employees to have the jab if they wanted one.

Following the vaccination I had the worst bout of flu I've ever had. Needless to say, I never had one ever again.....
I'll just avoid people and take my chances with flu and covid thank you. I have no wish to try and talk anyone else out of it, I'm not qualified, you do what you think is best.....

A virus can evolved into different strains, How do Dr's know it work on a new strain of the virus if the vaccine has not been tested against it?

They pick the strains that look most likely to hit the world in the season. Usually they seem to start in South East Asia and Australia.

They do test it works.

They don't always predict the right strains and when they occasionally get it wrong more people here die.

It doesn't cover you for all strains in the world just the top 3 or 4 (usually the worst culprits). That's one reason some people still get flu even if they have the vaccine, but it gives you a far better chance than not having a vaccine.

The virus they give you is dead so it cannot replicate.

Vaccination isn't just about self-protection but the protection of the wider group.

Don't take this personally Annie But, you can't use that old chestnut....
Your Health is Your responsibility, and putting your own health on the line because it might affect the wider group is nonsense. I believe that having the vaccine will seriously adverse my health, so I will not have one and I will not feel guilty, even though that is what that statement is trying to achieve....

With today's vaccinations there is a list of chemicals as long as your arm...In the fifties when I had all the usual vaccines you could count the number of additive on one hand. Why is that?
