Doomsday lies again.
Sariray, people who are specifically known to be allergic to specific vaccines should not receive them. But do you deny peanuts to normal babies who are not known to be allergic, just in case? On the contrary, it’s important for babies to be exposed to peanuts early, so they’re less likely to develop an allergy. The same applies to vaccines. Unless a child is known to be allergic to a specific vaccine, it should be given; those who are allergic will have to rely on herd immunity for whichever disease they couldn’t be vaccinated against, which means they depend on everyone else to be vaccinated.
