There are two recent studies that suggest that immunity lasts for at least a year and it is possible that it may last for decades, at least for some people. These studies have been made on bone marrow of the persons who have been infected by Corona virus Sars-CoV-2.
The first study on Persistent Cellular Immunity to SARS-CoV-2 Infection is as under:
SARS-CoV-2 is responsible for an ongoing pandemic that affected millions of individuals around the globe. To gain further understanding of the immune response in recovered individuals we measured T cell responses in paired samples obtained an average of 1.3 and 6.1 months after infection from 41 individuals. The data indicate that recovered individuals show persistent polyfunctional SARS-CoV-2 antigen specific memory that could contribute to rapid recall responses. In addition, recovered individuals show enduring immune alterations in relative numbers of CD4+ and CD8+ T cells, expression of activation/exhaustion markers, and cell division.
Summary We show that SARS-CoV-2 infection elicits broadly reactive and highly functional memory T cell responses that persist 6 months after infection. In addition, recovered individuals show enduring immune alterations in CD4+ and CD8+ T cells compartments.
The corona virus which started from Wuhan in China, decided not to visit any other province of China and seems to have been keeping that promise. No official of Chinese Communist Party came in contact with virus. No prominent leftist politician of influence got infected any where in the world, barring handful few exceptions. China except Wuhan could avoid infections but also it’s frequent and infamous and deadly variants.
India may be facing what is called second wave, has so far faced at least 7-10 variants. The present B-1.617 and B-1.617.2 have wrecked havoc. It happened last month like a cloud burst. Suddenly the active cases rose from on hundred thousand to three millions. And it is possible that this number leave out many with mild symptoms who could not be tested because of over load of work.
In all this mayhem, there is another pandemic, killing people or keeping them sick longer. This is called tele-medicina doctors. It is a new concept and there are no guide lines as to how the doctors should behave. The video call make it possible to observe the patient and all these electronic gadgets like Gluco-meter, Oxy-meter, Blood pressure monitors etc are providing good feedback but the Doctors have blown away the opportunity and created pandemic of their own. First of all the doctors seem to be obvious of simple protocols and SOPs of pandemic which are frequently released by AIIMS, Delhi for medical fraternity. All are available in videos but these Doctors are too smart or too busy to watch these videos. They do not care if a few patients die or live. After all it is the luck of patient.
Last year in April 2020 it was New York, overwhelmed with the deaths, it had the city’s permanent morgues and filled storage spaces in many hospitals to capacity. The Federal Emergency Management Agency deployed 85 refrigerated trucks to serve as temporary morgues. Since it happened in USA it was a matter of compassion and concern. There is a saying in India that a witch (dayan) too spares 7 houses in neighborhood. The media gang followed the rule. However the tempo of mismanagement continued till the elections in USA and suddenly after election there was nothing to report as head line in newspapers of USA.
India on the other hand is the new punching bag of the Global mafia of newspapers well supported by their henchmen in India, especially in Delhi. While these henchmen miss the States like Maharashtra, Kerala, Chhatisgarh due to their obvious leftist bias, they also always fail to mention that Maharashtra is still dealing with first wave which started last year and which never abated at all.
There is also no question asked as to how this Chinese virus from Wuhan is mutating so fast. Every few months it has a new mutation. It has never happened in history. How it is possible now? What is the role of China in this?
Here is a possible headline of a news about gross corruption which had never happened in India or elsewhere. It is the most glaring example of corruption:
” High Court orders Central Bureau of Investigation to investigate allegations of EXTORTION and ABUSE OF POWER against the Home Minister of Maharashtra, Anil Deshmukh”
It is official now. India is facing second wave of infections. Riding on the ‘Marriage Season” and gross violation of all protocols, the Corona Virus has hit India again. With 53,476 new cases and 251 deaths, the total infections rose to 11,787,534 cases which include 395,192 active cases and 160,692 fatalities, it is apparent. The number of daily infections has risen five times in less than a month.
The vaccination program of India and the world shows the total number of vaccinations so far:
SARS-CoV-2 was first reported from China. Within three months, it evolved to 10 additional subtypes. Two evolved subtypes (A2 and A2a) carry a non-synonymous Spike protein mutation (D614G).
A new study:
A phylodynamic analysis of over 70,000 SARS-CoV-2 coronaviruses worldwide, sequenced until July2020, and found that the mutant sub-type (614G) out competed the pre-existing type (614D), significantly faster in Europe and North-America than in East Asia. A study has concluded that:
