දැන් ඕක රුසියාවෙන් කියලා තියෙනවා නම් කිසිම ප්රශ්නෙකුත් නැත්තන් ඇයි මේකෙන් එක් මාත්රාවක් පමනක් ලබාගන්න කැමති කියලා අමුතුවෙන් අත්සන් ගන්නේ
What Gameleya (Sputnik developer) says is that for the moment you will be fine with just one dose....BUT their
main vaccine method is the two dose regime.
The single dose is for the third world countries like us, who are struggling to get the second dose.
A single dose is just a Primer - and many vaccine developers found that just the Primer works for a longer duration than previously envisaged. Even AZ extended their gap recently under these circumstances. A Booster plays an important part if administered within the gap period.
Nobody can predict what the future is.... That's why I always stress an anti-viral drug is the only way out. But Generation-3 DNA vaccines will play a big role when they get approved. Though the vaccines have been developed and also on trial, these will not be approved soon. Simply because the only instances where these has been used is for veterinary.
PS: Some of the comments in here stated how advanced the Chine vaccine is.. Ignorance is bliss. Both these vaccines are inactivated - Though the principle was by Edward Jenner, the first inactivated vaccines were in the 1950's.
The rest of the world went ahead with mRNA, Viral Vector, Protein SubUnit, DNA etc.... Sadly the Chinks only put an effort to develop new viruses.
