Вакцина против ВИЧ от Johnson & Johnson провалила исследование на второй стадии в Африке

Компания Johnson & Johnson заявила, что ее экспериментальная вакцина не смогла обеспечить достаточную защиту от ВИЧ для молодых женщин, которые подвержены высокому риску заражения.

В исследовании по тестированию вакцины приняли участие 2600 женщин из пяти стран юга Африки, где на долю женщин и девочек пришлось более 60% всех новых случаев ВИЧ-инфекции в прошлом году.

Испытание вакцины, основанной на аденовирусной конструкции, которую также использует вакцина против Covid-19 компании J&J, проводилось при поддержке Национального института аллергии и инфекционных заболеваний США и Фонда Билла и Мелинды Гейтс.

Исходя из полученных данных, компания J&J заявила, что исследование не будет продолжено. Участников исследования проинформируют о результатах и сообщат, получили ли они плацебо или вакцину.

Компания J&J заявила, что изучает безопасность и эффективность другого состава вакцины среди мужчин, имеющих половые контакты с мужчинами, и трансгендеров.

Telegram auto-delete message, expiring invites, and more

elegram is updating its messaging app with options for auto-deleting messages, expiring invite links, and new unlimited groups, the company shared in a blog post. Much like Signal, Telegram received a burst of new users in the confusion over WhatsApp’s privacy policy and now the company is adopting features that were already part of its competitors’ apps, features which offer more security and privacy. Auto-deleting messages were already possible in Telegram’s encrypted Secret Chats, but this new update for iOS and Android adds the option to make messages disappear in any kind of chat. Auto-delete can be enabled inside of chats, and set to delete either 24 hours or seven days after messages are sent. Auto-delete won’t remove every message though; if a message was sent before the feature was turned on, it’ll stick around. Telegram’s competitors have had similar features: WhatsApp introduced a feature in 2020 and Signal has had disappearing messages since at least 2016.
