I thought vaccines just contained antigens which are essentially just the receptors; i.e. it's impossible to actually get sick from a vaccine since the actual bacteria/virus is missing. IANAB though, I'm sure there are many kinds of vaccines prepared using many different methods.
Also, I thought the joke was funny; I highly doubt there are any genuine anti-vaxxers in HN comments.

Some are available in multiple forms, like Salk and Sabin polio vaccines. However, the risk of getting sick from the vaccine is small compared to the risk of getting sick without the vaccine. When the risk levels get close to equal, the vaccine type is changed to the less-risky but less-effective type. Attenuated virus vaccines are usually more effective than inactive virus ones.
