Вы не в курсе, что взрослым рекомендуется повторить прививку от ветрянки? Двукратная вакцинация и по Вашей ссылке упоминается, кстати.Кроме того, прочтите, что пишет CDC по поводу предварительной проверки уровня антител, если мне не верите.I don't think I have had chickenpox, but I am not sure. Is there a blood test available to determine whether or not I have had the disease?A blood test is available to check immunity, but it is not required before vaccination. However, since 70% to 90% of adults who do not remember having chickenpox actually have protection in their blood when tested, testing adults who do not have a reliable (e.g., healthcare provider verified) history of chickenpox may be cost saving. Ask your doctor about this blood test. If it is not available, it is still safe to receive the vaccine even if you have previously had chickenpox.
