Quick Answer. Seals protect themselves by using their sensitive ears to let them know when they should swim away from danger, and by using their sharp teeth and strong jaws to defend themselves if they need to fight. A seal's streamlined body allows them to swim away from predators at rapid speeds, which is typically how the seals stay away from predators.
The Shingles Vaccine. The shingles vaccine is a safe and easy, one-time shot that may keep you from getting shingles. Most people age 60 and older should get vaccinated. You should get the shot even if you already had shingles or donât remember having chickenpox. However, if you have a weak immune system or allergies to certain medicines, make sure to check with your doctor first. You can get the shingles vaccine at your doctorâs office and at some pharmacies.
What if you have never had chickenpox or have already had a case of shingles? You should still get vaccinated because studies show that nearly all adults 40 years and older have had chickenpox whether they remember having it or not. Also, if youâve already had shingles, the vaccine can help protect against recurrence.The vaccine is not safe for all people.he older you are when you have zoster, the more at risk of developing postherpetic neuralgia. âA lot of people get shingles and itâs relatively minor or moderate pain, and they get over it in a week. If that were the only risk, I would wonder about the overall usefulness of the vaccine ,â DiCarlo said.
