O/T:- ...Has the key to a coronavirus vaccine been staring us in the face?

What about those of us who have actually had TB are we more at risk or dosn't it matter

What about those of us who have actually had TB are we more at risk or dosn't it matter

My guess is that it would depend totally on the amount of lung damage incurred during the original TB attack (a vaccine causes no lung damage to my knowledge, merely provokes a response from the body's original immune system and that "memory" stops around for 15 to 20 years, or longer if given a booster jab.......even when totally faded, many believe that the body retains a faint "imprint" within it's innate or adaptive immune system)

With a full-blown attack of TB or pneumonia, it can leave scarring of the lung wall, permanent cavities or widening of the airways called bronchiectasis. Patients will always be short of breath and susceptible to respiratory diseases....so even if those with TB jabs are somehow less likely to catch Covid19, or more able to deal with it (there are now many reports of people actually getting Covid almost without knowing it, shrugging it off and acting as normal) the damage caused in the original attack could outweigh the benefits of any boosted auto-immunity.

Here is a report in the Lancet:
a study of more than 2,000 Indian patients with evidence of permanent lung damage.

Researchers have found that more than one-third of patients who are successfully cured of TB with antibiotics developed permanent lung damage which, in the worst cases, results in large holes in the lungs called cavities and widening of the airways called bronchiectasis.

TB survivors and patients with a history of severe infections such as childhood pneumonia made up the majority of patients with lung damage in India.

The research, funded by the British Lung Foundation and the European Respiratory Society, suggested that these infections left a legacy of daily cough, further chest infections and poor quality of life.
