Live-attenuated vaccines also need to be kept cool while they are stored, so they may not be suitable for use in environments where there is little access to refrigeration. Medical providers agree that the proven preventive benefits of vaccines far outweigh the risks of the minimal side effects associated with them. The Hepatitis B virus' DNA polymerase and retroviral reverse transcriptase are very similar and may have evolved from a common ancestor. They are suitable for people with weakened immune systems and long-term health conditions.

In extremely rare instances a high fever, in excess of 104 F, can occur with a vaccine. TLDR. If you need to go back and make any changes, you can always do so by going to our Privacy Policy page. Other strategies such as protein-based or inactivated vaccines also require chemicals and cell cultures . No vaccine offers 100% protection and vaccine efficacy meaning how well a vaccine prevents illness among those vaccinated varies from one type of vaccine to the next and how well a vaccine works also depends on the health status of the person vaccinated.
