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.
If you've already had shingles, the vaccine may help prevent it from coming back. The vaccine contains a weakened chickenpox virus, which doctors call the âvaricella-zosterâ virus. It primes your immune system to defend against the disease. Some people who get the vaccine still get shingles. But they're more likely to have shorter periods of shingles-related nerve pain called postherpetic neuralgia, which is very painful and can last weeks, months, or even years after the rash goes away.
