There is not a good reason.  It protects you, your close contacts and the nation and beyond.  Yet one in four Americans refuse a vaccine.  Millions of COVID shots have been given and the odds of dying after the vaccine are virtually nonexistent.  Social media has blurred the line making it difficult for some to judge the true risk. There is a significant amount of definitively false health claims including that the shots will change one's genetic material, although there is no genetic material in the shot.  Social media has claimed that microchips are being injected along with the protection.  On almost half of all the days in 2021, there is a story about someone dying after receiving the vaccine.  


Long-term serious side effects following any vaccine are extremely unlikely after a COVID vaccinations. Vaccine monitoring has historically shown that if side effects are going to happen, they generally happen within six weeks of receiving a dose.  For this reason during trials each of the vaccine recipients were studied for at least two months after the final dose.  Over 200 million doses have been administered and are undergoing the most intensive safety observation in U.S. history.  No long-term side effects have been detected.


The shots are almost 100% effective in preventing serious disease and death in those that receive it.  It is not yet known, but close contacts of persons who are vaccinated may not spread the virus to another even when the vaccine is infected, but not ill.  If enough people are vaccinated, those who are susceptible but cannot get vaccinated are protected because the germ will not be able to find those susceptible individuals.   As of the end of March 2021 a total of about 20% of the U.S. population had been fully vaccinated.  It is not known because diseases have their own percentage of when herd immunity will occur.  The estimates are between 50 to 85% of the population will need to be vaccinated or have had the disease for COVID 19 to reach herd immunity.
