Many vaccines against COVID have been in the works since it became clear that SARS-CoV-2 was not going to fade away quietly like the previous MERS and SARS outbreaks did. Three days ago, Novavax announced that its phase 3 clinical trials from the UK showed their vaccine to be 89.3% effective, making it the third company to produce a highly effective vaccine following Pfizer and Moderna. This vaccine is different from the Pfizer and Moderna vaccines in that it consists of nanoparticles formed from artificially synthesized virus spike proteins. This vaccine development strategy has been used to make many other vaccines such as those for influenza and HPV.
An important complication to note is that this vaccine was tested in a small group (~4,000 people) in South Africa and was found to be only about 60% effective. Of those who contracted the virus during the South Africa trial, more than 90% were infected with the region’s new variant. This is concerning because as the virus gets more exposure to vaccine-induced immunity, the odds that it mutates to the point that it can fully escape the vaccine increase. Even if the vaccine is less effective against new strains, however, 60% protection can make a critical difference in efforts to slow the virus’ spread especially when vaccine availability is a problem. Novavax, however, has acknowledged that it may need to return to the drawing board.
For Novavax, returning to the drawing board means another round of a long, expensive design and production process. Synthesizing protein for their vaccine is done biologically using cells whereas the RNA vaccines created by Pfizer and Moderna are synthesized chemically which is usually faster and cheaper. It’s interesting to note that RNA vaccines are a new technology making their debut in the attack against SARS-CoV-2. The development of this novel type of vaccine is likely just one of many scientific developments that will arise from the huge amount of effort, funding, and motivation that has been directed at this virus.

I was a HIV-AIDS patient and I got it from cheating on my wife. It was sort of a payback but a week later I was told by a friend that the person who I cheated with had the HIV-AIDS virus and did not tell me. I was so stupid by not using a condom I thought since he was an old school friend he was trustworthy. But I was wrong. I cried and cried. Two days later, I got a phone call from my friend and he told me about a person who is known by another friend, who can help me. I could not let my wife know what I was going through. I finally got his email address: oseremenspelltemple@gmail.com and I emailed this man my story and he replied me immediately saying i should be calm and told me that everything will be OK. I could not come to terms with what I was hearing but then I concluded it did not matter because I was so broken I just needed help. I was going out of my mind literally. I was confused with what he was telling me, but I listened. He told me about some materials i need to buy that he needed to cast the spell and I said OK. I bought the materials to him, I sent down my picture to him and my positive result sheet and he replied me that i am going to be negative under 3days. I message Him every 2hours for 2day and I knew he thought that I was crazy but I did care I needed a shoulder. Behold, the third day he messaged me i should go for a test that i will be negative. My marriage could be broken because of a stupid mistake and my life was on the line. I remembered when I was going to get the results of my re-test I called him up again and told him that I was going to get my results today and his reply was “so" and that everything will be as he explained. I knew then that he was getting tired of me calling him, maybe I was wrong. Well I got my results and the first person I called was him - again. As he said hello I started to cry and cry. I could not believe it. I was given a second chance in life.This man is a great spiritual HIV/AIDS healer, his healing spell on aids healing is very powerful .please brothers and sister, contact Dr Ose oseremenspelltemple@gmail.com
