It is a form of vaccination but many people who are anti-vax are mostly concerned with things like thimersol. That isn't universal. Like any group, there are a wide variety of views within the anti-vax crowd. Some people think that spacing them out is important. Some people think that vaccines are okay as long as they don't have certain additives. Some people think it's not just the additives but the vaccines themselves.
> No, measles, mumps, and rubella (MMR) vaccines do not and never did contain thimerosal. Varicella (chickenpox), inactivated polio (IPV), and pneumococcal conjugate vaccines have also never contained thimerosal.
Additionally, you get more mercury from breathing in pollution from coal burning power plants than you ever will from vaccinations.
Folks who are concerned about things like thimersol are typically also very concerned about other sources of metal poisoning. And that's a whole other ball of wax that's quite controversial.
Avoiding vaccinations due to scientifically unsupported fears (and often blatantly wrong information, like that MMR ever had thimerosal) about mercury and other preservatives is like avoiding breathing to prevent pollution poisoning. Neither one makes much sense.
