What did an American woman infected with the emerging coronavirus, Covid-19, begged, through her account on Tik Tok, to her followers before her death?

What are the latest data on the effectiveness of vaccines against the Delta strain of Corona, and which vaccines are more effective: Pfizer-Biontech, Moderna, or Johnson & Johnson?

The answers and more are in this comprehensive report.

We start from Tik Tok, where a woman infected with the Corona virus begged her followers, while she was on her bed, to seek the vaccine, 9 days before her death, stressing the need to receive the vaccines without delay.

"I don't have much energy to talk...so I'll try to make this quick, I didn't get vaccinated, I'm not against the vaccine," said the woman, Megan Alexandra Blankenbiller, 31, in her letter.

I was just trying to do research and was scared, as verified by Sanad Agency in Al Jazeera Network.

She added, "I think waiting was a mistake. I shouldn't have waited. If you're 70% sure you want the vaccine, go get it, don't wait.. Go get it. I hope if you get it, you won't end up in the hospital like me." .

And after 9 days of publishing the clip, which achieved more than a million views, her sister Christina Blankenbiller said in a post on her Facebook: My friends .. As most of you know, I am a very closed person, but I ask for your help in sending prayers to my family and my older sister ..

Soon, Christina announced the news of her sister's death in another post, which she later deleted, in which she said thank you all for your prayers for my family.. I feel sad and broken because I share that my older sister has been invited to heaven today.

She continued, "Meghan was a beautiful person who gave everything to anyone in need."

She was a light to everyone around her and brought joy to everyone she met, she was so lovable, she was the best big sister and friend anyone could ask for, not a day goes by without you on my mind and in my heart.

The risk of death is reduced

We turn to the latest research, as the US health authorities have confirmed that the risk of death as a result of Covid decreases by 11 times and the probability of transferring the injured to hospitals by 10 times among people who have received full doses of anti-vaccines.

The data came from 3 new research published by the Centers for Disease Control and Prevention in the United States on Friday, and reported by the French press agency, and all confirmed the effectiveness of Covid vaccines in preventing any severe complications in the event of an epidemic.

For reasons that are still poorly understood, the data indicate that the Moderna vaccine provided a higher degree of protection in light of the spread of the delta mutant.

"As we've shown in study after study, vaccines are effective," Centers for Disease Control and Prevention Director Rochelle Wallensky told reporters Friday.

The first study looked at hundreds of thousands of cases in 13 US regions from April 4 to June 19, the period before the delta mutation, and compared it to the period between June 20 and July 17.

Between the two periods, a slightly vaccinated person with Covid increased from 11 times less likely to infection compared to the unvaccinated to 5 times.

And the protection against the development of the condition to the extent that requires the patient to be transferred to the hospital and death remained more stable, but it declined more among adults 65 years and over compared to the younger ones.

One study, which evaluated vaccine efficacy from June through August in more than 400 hospitals, emergency departments, and urgent healthcare clinics, ranked the efficacy of vaccines by brand.

Effectiveness against the need for hospital transfer was highest for Moderna (95%), then Pfizer (80%), and finally Johnson & Johnson (60%).

The overall effectiveness of preventing the need for hospital transportation was 86% for all age groups, but the percentage declined to 76% among adults 75 years and older.

The Pfizer and Moderna vaccines, which use RNA technology, have often performed somewhat better than Johnson & Johnson, which is based on a modified adenovirus, and is likely given in a single dose.

But it is still not clear why Moderna is somewhat superior to Pfizer in the face of the mutated Delta.

It may have something to do with higher dose concentrations (100 mcg vs. 30) or a longer interval between doses (4 weeks vs. 3), which is associated with a stronger immune response.

Mixed Vaccines

The United Kingdom is preparing to start a program to administer mixed and identical vaccines against the Corona virus, as booster doses, according to the German news agency quoted the Financial Times, quoting prominent government figures.

On Friday, Bloomberg News Agency quoted those government figures as telling the newspaper that a third, different dose booster for the first two doses will provide better protection against the virus.

The government will make a final decision on the booster dose plan, after the Joint Committee on Vaccines and Immunity makes its recommendation.

An unidentified senior official from the Ministry of Health told the newspaper that people who received the AstraZeneca vaccine () for the first time, will receive the Pfizer vaccine, as a booster dose, while those who received Pfizer will receive AstraZeneca.

The Ministry of Health told the newspaper that it will continue to prepare for the booster dose program for the fall, and that any such program includes what vaccines may be recommended for use, and will depend on the final advice of the Joint Committee on Vaccines and Immunity.

In the world

Globally, more than 5.63 billion people have received doses of the vaccine against the Corona virus so far in 184 countries, among the largest vaccination campaign in the history of the world, according to data compiled by Bloomberg News Agency on Friday.

The most recent rate of vaccinations was nearly 35 million doses per day.

With this number of global doses, 36.6% of the world's population has been fully vaccinated against the Corona virus.

But the distribution has been uneven, with higher income countries and regions getting vaccinated more than 20 times faster than lower income countries and regions.
