3rd vaccine safe if 1st and 2nd were?

[JollyJoon]

If you had the first and second vaccine (same vaccine) with zero negative effects on your health/body, does that mean its 100% guaranteed that you cannot have negative effects from the booster (same vaccine)?

Basically if you were going to have issues such as clotting would you have necessarily seen those with the first jab?

I don't think there's ever a 100% guarantee, but I would say it was unlikely if you have already had 2 that were fine and you are getting the same again.

There are vanishingly few things which carry a 100% guarantee in life, I think only death and faxes really qualify.

If the first two vaccines didn't cause any issues, why would you expect the third to do so?

Research has shown far fewer clotting problems with the second jab than the first with the astrazenica vaccine.

You could choke on the next steak you eat. Or crash in the next plane.

You're unlikely to have a random new allergic reaction but it's still possible.

The clotting issues were with AZ and I don't believe that is being used for boosters.

I had zero side affects with first
A headache so bad I spent a night in hospital with the second
I had zero side affects with third

Even after my bad experience with the second I did not hesitate to get my booster.

There are no 100% guarantees about anything in life.
