CDC announced a few changes to the vaccine guidelines for adults. The new guidelines highlight the need to take flu shots including for people with egg allergy.

1. Nasal spray no more

Nasal flu vaccine was one of the recommended prevention but it was found to have a poor result. The immunization is now revised as per recommendations from a group of health experts in Advisory Committee on Immunization Practices (ACIP). CDC now recommends the traditional flu shots.

2. Flu vaccine for people with egg allergy

Whether it is a mild or severe allergy, CDC has made a change in its recommendation to 'age-appropriate' instead of choosing egg-free vaccine.

3. HPV vaccine

CDC also updates HPV vaccine, recommending three doses for teens and adults who just start getting the vaccine at the age between 15 and 26, ABC News reported.

In addition to that, CDC also made a few changes in meningitis vaccine, suggesting that adults should receive two doses. During an outbreak, the doses are increased to three.

All shots should be done under a health care supervision especially those with a specific allergic condition.

According to ACIP, the guidelines have been changed since not all adults are getting the shots. For instance, the advisory committee has noted that only 44 percent adults received flu vaccines. Moreover, physicians found that age-appropriate recommendations were difficult to follow.
