Second vaccine dose must if you get Covid after first jab: DAK

(Asian News Hub) – If you have received first dose of Covid-19 vaccine and got infected with the virus, you should go for the second shot soon after the recovery,”said Doctors Association Kashmir (DAK) on Tuesday in a communiqué.

“People who contract Covid after the first dose still need to get the second jab,” said DAK President and influenza expert Dr Nisar ul Hassan.

“However, you shouldn’t get the vaccine while sick,” he said.

Dr Hassan said you should get your second dose as soon as your isolation is over.

“One should take the second shot 2 weeks after all the symptoms of Covid have been resolved,” he said.

“I am aware of several cases where someone tested positive for Covid-19 after getting their first dose,” Dr Hassan said.

“They should get their second dose of the vaccine after they get over with their quarantine to gain its full protective benefits,” he said.

The DAK President said you are fully protected against the Covid only after the second dose.

“It is vitally important to get both doses for best protection against the Covid,” he said.

“First dose primes the body with an initial immune response,” Dr Nisar said.

“Second dose is the one that really gives the boost to the immune system. It induces a level of virus neutralizing antibodies about 10-fold greater than the first dose,” he said.

“Also, second dose induces cellular immunity, which predicts not only longer protection, but better protection against variant strains,” he added.

Dr Nisar said there are two Covid-19 vaccines that are being used in Kashmir right now – Covaxin and Covishield which have two-dose schedule.

He said doses are spaced depending on which vaccine you get. ​ ​

“The time interval between two doses of Covaxin is 4-6 weeks, while second dose of Covishield can be taken 4-8 weeks after the first. But, there is some data that delaying the second dose of Covishield up to 12 weeks gives a better immune boost,” he informed.

“It is imperative to take the same vaccine for both doses and mixing of the two should not be done,” he added.

New Coronavirus found in bats in china, Scientists worried

(Asian News Hub) – In a shocking revelation, Chinese researchers claim to have found a batch of new coronaviruses in bats. They even say that the newly found viruses in the bats include one that may be the second-closest yet (genetically) to the COVID-19 virus, reports CNN.

According to the researchers, their discoveries in a single, small region of Yunnan province, southwestern China show just how many coronaviruses there are in bats and how many have the potential to spread to people.

In a report published in the journal Cell, the Chinese researchers from Shandong University said, “In total, we assembled 24 novel coronavirus genomes from different bat species, including four SARS-CoV-2 like coronaviruses.”

One was very similar, genetically to the SARS-CoV-2 virus that’s the cause of the current COVID-19 pandemic, they said.

It would be the closest strain to SARS-CoV-2 except for genetic differences on the spike protein, the knob-like structure that the virus uses when attaching to cells, they said.

Researchers are trying to find where SARS-CoV-2 came from. Although a bat is a likely source, it’s possible the virus infected an intermediary animal. The SARS virus that caused an outbreak in 2002-2004 was tracked to an animal called a civet cat.

Three of the samples described in Thursday’s report were also close to SARS genetically.

This discovery of new coronaviruses in bats comes at a time when scientists and countries across the world are calling for further investigations to figure out whether the virus originated naturally or leaked from the Wuhan Institute of Virology.

Covid-19 patients testing positive after recovery can’t transmit virus to others: DAK

(Asian News Hub) – The Doctors Association Kashmir (DAK) on Friday said some Covid-19 patients test positive weeks after recovering from the infection.

“RT-PCR test can detect the virus weeks after Covid patients have recovered from the illness,” said DAK President and influenza expert Dr Nisar ul Hassan.

“That does not mean that a person is infectious and able to transmit the virus to another person,” he said.

Dr Hassan said in most Covid-19 positive cases, the virus dies after the 7th or the 8th day of the illness. At that time virus cannot be transmitted to another person.

“But the dead virus can still be picked up by RT PCR test and the report may still come positive, even when a person has become free from Covid,” he said.

“RT-PCR test which is used to detect Covid-19 cannot distinguish whether the virus in the patient is dead or alive,” Dr Hassan said.

He said virus culture can tell us whether the positive test has picked up active virus which can reproduce and spread or just dead virus which won’t transmit to others.

Quoting a Korean study, DAK President said people who had recovered from Covid and tested positive again were not found to be contagious. That means they didn’t transmit the virus to others, based on virus culture that failed to find live viruses in recovered patients.

“Testing positive after recovery has caused a lot of unnecessary stress and panic among recovered Covid-19 persons,” he said.

Dr Nisar said in order to avoid unnecessary prolonged isolation and unnecessary use of laboratory testing resources, retesting is not recommended now. There is a shift from test-based strategy to time-based and symptom-based strategy to end the isolation of Covid patients.

“Under the new guidelines, Covid patients have to remain in isolation for 10 days after the symptom onset plus at least 3 additional days without symptoms,” he said.

“The initial recommendation to confirm clearance of the virus and thus allow discharge from isolation, required a patient to be clinically recovered and to have two negative RT-PCR test results on sequential samples taken at least 24 hours apart,” he added.

Third COVID-19 wave could be as severe as second: SBI report

Children could be the next vulnerable group and vaccination for them should be speeded up

(Asian News Hub) – The third wave of the novel coronavirus disease (COVID-19) in India could be as intense as the second wave and it could last for an average duration of 98 days, according to a new report released by the State Bank of India (SBI) June 1, 2021.

However, the impact can be minimised if the number of serious cases are arrested by prioritising two things — improvement in health infrastructure and vaccination, it added.

The report pointed out that the average duration of the third wave for developed countries was 98 days and that of the second wave was 108 days.

However, it is also observed that in the third wave, if we are better prepared, the decline in serious case rate (patients that require oxygen, intensive care unit beds, etc) will lead to fewer deaths. We find that if serious cases decline from 20 per cent to 5 per cent (due to better health infrastructure and rigorous vaccination) in the third wave, the number of deaths in the third wave could significantly reduce to 40,000, as compared to the current deaths of more than 0.17 million.

It also warned that children could be the next vulnerable group and that vaccination should be the key priority, especially for them.

“With around 150-170 million children in the 12-18 age bracket, India should go for an advanced procurement strategy like that adopted by developed nations to inoculate this age-group,” the SBI Ecowrap report said.

The SBI economists slashed the gross domestic product growth estimates for (financial year) 2022 to 7.9 per cent, from the earlier projection of 10.4 per cent. But it has not taken into account the possibility of a third wave in its analysis.

Meanwhile, India continues to record over a 100,000 cases per day. In the last 24 hours, India recorded 132,788 new COVID-19 cases and 3,207 deaths. Tamil Nadu added the maximum cases (26,500) to the country’s case load, followed by Kerala (19,760) and Maharashtra (14,123).

The total number of active cases stands at about 1.79 million right now.
