No. Many people have no symptoms at all. If people are going to have symptoms, the most common have been soreness at the site of vaccination, headaches and fatigue. Some people have had body aches and rarely (less than 10%) people have had chills and/or a fever. If people are going to have side effects, they typically start 1-2 days after vaccination and last for 1-2 days. Some people have had more side effects with the second dose of vaccine but again the side effects are short lasting. One could think of the symptoms described above are a good thing as it is a sign that the vaccine is working. While we would prefer that no one who received the vaccine had any side effects, we think the benefit of protection against a potentially lethal virus FAR outweighs the possible risks of the vaccine.
