There is something quite amazing about your link however. The piece (about long term side effects from vaccines) notes the polio vaccine from the 1950s. It somehow omits mentioning Simian Virus 40, the cancer causing virus that was found in the polio vaccine. This vaccine was given to 100 million children and its estimated that 10% to 30% of those doses were contaminated.
I'm sure the doctors assured their parents back then that there were no side effects and certainly laughed off any mention of long term side effects. The price to be paid for trust in these vaccines? Their children growing up to develop brain cancer in their 50s and 60s, decades after they were assured how safe they were.
And nice whataboutism to switch the topic to a vaccine incident from the 1950s, combined with a brand new account, I'm pretty sure I'm arguing with a bot. Have a nice life.
The link I supplied was literally a source:

> 2. Vaccine side effects show up within weeks if at all
> That is not to say that there have never been safety issues with vaccines. But in each instance, these have appeared soon after widespread use of the vaccine began. "The side effects that we see occur early on and that's it," Goepfert said. In virtually all cases, vaccine side effects are seen within the first two months after rollout.
That is citing the director of the University's Vaccine Research Clinic.
