COVID-19 vaccines are unique because of the way they inform the body about the virus.
However, AstraZeneca and Novavax are working toward becoming top vaccine producers and distributors, too.
COVID-19 vaccines can come with a number of side effects, but they’re nothing too horrible.

This syndrome, Guillain-Barre syndrome, has been identified in an estimated 100 people who received the one-dose vaccine.
Its symptoms can last anywhere from a few weeks to a few years.
“Most people recover fully, but some have permanent nerve damage.

Some people have died of GBS,” the CDC warns.
This syndrome can also lead to paralysis, as your muscles continue to be attacked by your immune system.
