What is “Breakthrough Infection”?

What is the News? 

The union health ministry has said that the breakthrough infection rate is low for both Covaxin and Covishield vaccines.

What is it?

  • Breakthrough infection is a case of illness in which a vaccinated individual becomes sick from the same disease for which the vaccine was administered.
  • Simply, it occurs when vaccines fail to provide immunity against the pathogen they are designed to target.

Possible Reasons for Breakthrough Infections:

  • India’s healthcare and frontline workers were on the priority list for vaccination during the first phase. They were always prone to more occupational exposure to the coronavirus disease.
  • The second wave of Covid-19 is highly transmissible, it might also have contributed to the breakthrough infection rates.

India’s Breakthrough Infections Data:

  • Covishield: After the first dose two per 10,000 people get reinfected and after the second dose, three per 10,000 people get reinfected.
  • Covaxin: After the first dose four per 10,000 people get reinfected after the number remains the same for the second dose too.
  • This type of Infections are mostly mild or asymptomatic because the individuals still have partial protection.


  • According to a US study, people with no symptoms transmit more than half of all cases. This means that controlling this silent transmission from persons without symptoms is very important for controlling the pandemic.
  • Hence, it is very possible that an asymptomatic breakthrough infection can result in the further spread of the disease in the community.
  • This happens especially because people may become careless following vaccination and many such infections are asymptomatic.

What are “Oxygen concentrators” and how are they different from Oxygen cylinders?

What is the News? 

Currently, Oxygen concentrators are in much demand for oxygen therapy. Demand is high especially among patients in home isolation and for hospitals running out of oxygen.

About Oxygen Concentrators:

  • Oxygen Concentrator is a medical device. It filters oxygen from the atmosphere and helps individuals inhale it through a mask or cannula.

How does it work?

  • Atmospheric air has about 78% nitrogen and 21% oxygen with other gases making up the remaining 1%.
  • The concentrator takes in this atmospheric air, filters it through a sieve. Further, it releases the nitrogen back into the air and works on the remaining oxygen.
  • This oxygen compressed and dispensed through a cannula, is 90-95% pure.
  • A pressure valve in concentrators helps regulate supply, ranging from 1-10 litres of oxygen per minute.

How is it different from oxygen cylinders and LMO?

  • The oxygen cylinder gives you a finite amount of oxygen. When the cylinder is empty, it needs to be refilled. Whereas the concentrator pulls oxygen from the air. So it can provide a consistent supply of oxygen, and it only needs a power source to draw in Atmospheric air.
  • Oxygen Concentrators are portable and need no special temperature. On the other hand, Liquid Medical Oxygen(LMO) needs to be stored and transported in cryogenic tankers.
  • Oxygen from Concentrators is not as pure as Liquid Medical Oxygen (LMO) which is a 99% pure oxygen. But it is good enough for mild and moderate Covid-19 patients with oxygen saturation levels of 85% or above. However, it is not advisable for ICU patients.
  • Oxygen concentrators are the easiest alternatives to cylinders but can only supply 5-10 liters of oxygen per minute (critical patients may need 40-50 liters per minute).
  • Oxygen Concentrators are more expensive than Oxygen cylinders. But it is largely a one-time investment. Apart from electricity and routine maintenance, there is a little operational cost. While oxygen cylinders incur refilling and transportation costs.

  • Findings: According to the report, 8 of the 21 E-2020 member countries reported zero indigenous cases of human malaria by the end of 2020. However, the progress was disrupted due to the COVID-19 pandemic.

About E-2025 initiative:

  • Building on the successes of the E-2020, WHO has launched the E-2025 initiative.
  • As part of this initiative, WHO has identified 25 countries that have the potential to eliminate malaria within a 5-year timeline.
  • The countries will receive technical and on-the-ground support by WHO and its partners, in their work towards the target of zero malaria.
  • In return, the countries will audit their elimination programs annually, participate in elimination forums, conduct surveillance assessments, and share malaria case data periodically.

“Oxygen Express” Trains – Railways Waive off Few Charges

What is the News?

Indian Railways has decided to waive certain charges on ‘Oxygen Express’ trains. This decision is important due to the increase in demand for Liquid Oxygen from major hospitals across the country.

Oxygen Express:

  • Oxygen Express is a special train transporting liquid medical oxygen to states and Union Territories in cryogenic tankers.
  • It was started to meet the high demand for liquid Medical oxygen gas for the treatment of coronavirus patients.

Why Transport of Liquid Oxygen through train?

  • Transportation of oxygen through trains is faster over long distances than road transport.
  • Transportation through rail takes 2 days. On the other hand, transportation through the road takes 3 days.
  • Further, trains can run 24 hours a day but truck drivers need to take halts.


  • Oxygen in a cryogenic state is a hazardous chemical. Hence, Railways have to avoid sudden acceleration, deceleration to check pressures in between especially when it is in a loaded condition.
