۷۱ سال قبل در ۲۶ مارس ۱۹۵۳، در یک روز مهم در تاریخ پزشکی، دکتر Jonas Salk از آمریکا اعلام کرد که اولین واکسن فلج اطفال (از ویروس غیر فعال) را ساخته است.

او واکسن را روی خود و خانواده‌اش تست کرد و تا یک سال بعد روی ۱/۶ میلیون نفر در آمریکا، کانادا و فنلاند تست شد و نتایج هم در ۱۹۵۵ اعلام شد. شش شرکت دارویی مجوز ساخت واکسن را دریافت کردند ولی او نخواست تا سودی از به اشتراک گذاری اطلاعات واکسن دریافت کند و وقتی از او پرسیدند که صاحب امتیاز واکسن کیست، پاسخ داد که متعلق به مردم است و مگر مثلا خورشید Patent دارد!

تعداد افراد مبتلا به این بیماری از ۵۸ هزار مورد در ۱۹۵۲، به حدود ۶ هزار مورد در ۱۹۵۷ و تنها ۱۶۱ مورد در ۱۹۶۱ رسید.
در بزرگترین همه‌گیری ثبت شده در آمریکا بیش از ۳۰۰۰ نفر در ۱۹۵۲ به علت ابتلا به این بیماری فوت شده بودند.

بعدا واکسن دیگری توسط Albert Sabin (قطره خوراکی از ویروس زنده ضعیف شده) در ۱۹۶۲ ساخته شد. (از ایکس و‌ WHO)

One of them is telegram-group.com. This website has many categories and a really simple user interface. Another great site is telegram channels.me. It has even more channels than the previous one, and an even better user experience.These are just some of the many available websites. You can look them up online if you’re not satisfied with these two. All of these sites list only public channels.

Telegram Q&A

Q: How does hottg.com work?

Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. You can write to your phone contacts and find people by their usernames. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. In addition to this, we support end-to-end encrypted voice calls.

Q: What is Telegram? What do I do here?

Telegram is a messaging app with a focus on speed and security, it’s super-fast, simple and free. You can use Telegram on all your devices at the same time — your messages sync seamlessly across any number of your phones, tablets or computers.

Q: Who is Telegram for?

Telegram is for everyone who wants fast and reliable messaging and calls. Business users and small teams may like the large groups, usernames, desktop apps and powerful file sharing options. You can appoint admins with advanced tools to help these communities prosper in peace. Public groups can be joined by anyone and are powerful platforms for discussions and collecting feedback.In case you're more into pictures, Telegram has animated gif search, a state of the art photo editor, and an open sticker platform (find some cool stickers here or here). What's more, there is no need to worry about disk space on your device. With Telegram's cloud support and cache management options, Telegram can take up nearly zero space on your phone.

Q: How is Telegram different from WhatsApp?

Unlike WhatsApp, Telegram is a cloud-based messenger with seamless sync. As a result, you can access your messages from several devices at once, including tablets and computers, and share an unlimited number of photos, videos and files (doc, zip, mp3, etc.) of up to 2 GB each. And if you don't want to store all that data on your device, you can always keep it in the cloud.Thanks to our multi-data center infrastructure and encryption, Telegram is faster and way more secure. On top of that, Telegram is free and will stay free — no ads, no subscription fees, forever.

Q: Can I make calls via Telegram?

Yes! Voice calls are currently available to users around the world.
