Также показательным является большое количество больниц, которые когда-то запретили использование сотового телефона и теперь не заморачиваюсь. Что ваше исследование до сих пор не дал? ну, а кто-то очень умный сказал - Все относительно :) @GregMcNulty рода. Это потому, что вы не вручаете награду (или принять мой ответ) до конца льготного периода. @CareyGregory, я вижу, я добавил ссылку на другую страницу, надеясь, что это можно свободно добраться. Ваша точка предоставляя текст очень правильный, однако, у меня нет медицинского опыта и я не смогу предоставить научный ответ, я задал вопрос, поэтому я не мог подробнее рассказать об ответе. Когда я добавил редактировать на вопрос, мне посоветовали создать ответ. Ваша точка зрения все еще действует. Я голосую, чтобы закрыть ваш вопрос, так как неясно и правда это потому, что вы отвечаете на ввод в комментарии и ответы, что является **весьма актуальна** на вопрос, ты писал о том, что именно "не имеет значения" - если ты хотел задать другой вопрос, пожалуйста, спросите, что вместо одного.

Это, как правило, другим штаммом гриппа или ОРЗ.

К сожалению, вирусы, как грипп, способны комбинировать и рекомбинировать свои гены практически бесконечно, что означает, что они в конечном итоге с разных белков на их внешний слой.

Те белки, которые организм распознает вирус как иностранный захватчик, так и другой тип белка означает, что наш организм не распознает вирус. Вакцины против гриппа каждый год, по сути, пытается подвергать свой организм белками из многих из новых штаммов гриппа, для того, чтобы уменьшить шансы заражения. Потому что есть очень много штаммов гриппа, хотя вакцина является единственным эффективным при предотвращении примерно в 60% случаев (все-таки огромное достижение!).

Однако важно также отметить, что иммунитет ко многим болезням-это не навсегда. Некоторые заболевания, или вакцины против болезней (по сложным причинам) вызывают более короткий период иммунитета. Другими словами, организм "забывает" разоблачение рано. Вот почему вы должны регулярно получать от прививки от столбняка вакцины, например.

Хотя вполне возможно потерять иммунитет, большинство простуд и гриппа приходят из мутаций вируса, которые наш организм не может распознать.
