Covishield is the Oxford-AstraZeneca vaccine which is locally manufactured by the Serum Institute of India. Serum institute India is the world’s largest vaccine manufacturer.

It had already said that it is producing more than 50 million Covishield vaccine doses a month.

The Covishield™ by AstraZeneca is already used in clinical trials where the participants received one or two doses in overseas and Indian trials.

These Clinical trials are a three-phased process to determine whether the vaccine induces good immune responses and whether it causes any unacceptable side-effects.

What is Covishield?

Covishield vaccine is made from a weakened version of a common cold virus also known as an adenovirus from chimpanzees. It has been modified in the lab to look more like coronavirus – although it can’t cause illness.

The Vaccine making company, Serum Institute (SII), says that it is highly effective and backed by phase III trial data from Brazil and United Kingdom.

how does Covishield work?

When the vaccine is injected into the person, it activates the immune system of the person’s body. Then our bodies start to make antibodies against the virus. This antibody is targeted on the attack to any type of coronavirus infected towards our body.

Dosage of Covishield Vaccine

The covishield vaccine is administered as two doses given between four and 12 weeks apart.

When you receive one dose of the Covishield vaccine, then the second dose should be taken between 4 to 6 weeks after the first dose.

However, you can take the second dose up to 12 weeks after the first dose from according to different studies.

When you miss your second dose, you need to ask your healthcare provider for further advice on how you complete the dose.

Contents of Covishield Vaccine

The contents of the covishield vaccine contain the following contents:

  • L-Histidine
  • L-Histidine hydrochloride monohydrate
  • Magnesium chloride hexahydrate
  • Polysorbate 80
  • Ethanol
  • Sucrose
  • Sodium chloride
  • Disodium edetate dihydrate (EDTA)
  • Water for injection.

Storing of Covishield Vaccine

This vaccine can be stored at temperatures of 2C to 8C safely. This means that it can be stored about the same as a domestic refrigerator. The easy storing makes easier to store as well as distribute in comparison to another version of vaccines by other countries.

The vaccine which is developed by Pfizer-BioNTech company must be stored below -70 degree centigrade which is a challenge for developing countries like India, Nepal, Bangladesh, Maldives, Srilanka, and other

Effectiveness of Covishield?

As per the previous International clinical trials of the Oxford-AstraZeneca vaccine, it showed that the effectiveness hit 90% on its half and full dose. But as it’s new and is in the trial phase, there was not enough clear data.

However, the data shows that given the vaccine in different trials was found to be 70% effective after the first dose.

Who can take the Covishield vaccine?

Covishield vaccine has been approved for restricted use in an emergency in individuals 18 years of age and older.

Who should not take the Covishield vaccine?

The person with the following medical conditions and other conditions shouldn’t take the covishield vaccine. If you are planning to take the vaccine, then you should tell the health care provider or the person who is giving you the vaccine.

  • When you have an allergic reaction (anaphylaxis) of any drug
  • If you have a severe allergic reaction on the previous dose of the COVID vaccine
  • If you are allergic to food or other materials
  • If you get an allergy to any type of vaccine or any
  • If you are allergic to the contents and ingredients of the COVISHIELD™ vaccine
  • If you have a fever
  • If you have a bleeding disorder
  • If you are taking blood thinner medicine like aspirin, clopet, warfarin, and so on.
  • If you are immunocompromised patients
  • If you are taking the medicine that affects your immune system like anti-cancer drugs, DMRD for Rheumatic Arthritis, immune disease
  • If you are pregnant else, you plan to become pregnant
  • If you are a breastfeeding mother

Summary,

The corona vaccine has been made by multiple companies. Many trials have been still in progress on the effectiveness of the vaccine. The Covishield vaccine is also in trails phase and had already completed 2nd and 3rd trials with good response and effectiveness.

As the data is not so sufficient, the adverse effect following the covishield vaccination is found to be not much to be worried about. Can know more about Covishield Factsheet The preceding data will surely come into existence in the following days.

Simultaneous palpation of two pulses can be diagnostic in radiofemoral delay. Normally the femoral and the radial pulses occur simultaneously.When the femoral pulse lags behind the radial (radio-femoral delay), occlusion of the aorta either due to coarctation or atherosclerosis is diagnosed. Reduced amplitude and delayed timing of the pulses in the lower body compared to the pulses in the upper body are classic features of aortic coarctation. All hypertensive patients should be examined for radiofemoral delay. Unilateral absence of a pulse can aid in the diagnosis of a dissected aortic aneurysm.
Radial pulse is located on the lateral of the wrist (radial artery). This can also be found in the anatomical snuff box.
Femoral pulse is located in the inner thigh, at the mid-inguinal point, halfway between the pubic symphysis and anterior superior iliac spine (femoral artery).
Diminished or absent femoral pulses indicating proximal occlusion is often seen in peripheral vascular disease.
What is the mechanism of radiofemoral delay?
Radiofemoral Delay
Similar to aortic stenosis, coarctation of aorta cause a decrease in the rate of ejection of blood because of narrowing of vessel and the Venturi effect sucking the vessel walls inwards, it will create a reduction in the flow and amplitude of the pulse distal to the occlusion.
Delay
In addition, the following factors are essential in the mechanism of a pulse that is seen in any type of coarctation
The coarctation creates a pulse wave reflection sitewhich is much closer to the heart. This means the pulse wave is reflected earlier and faster, resulting in a higher blood pressure proximal to the stricture.
There are fewer cushioning properties (i.e. less compliance of the arterial segment involved
proximal to the coarctation), this will further increase blood pressure at or just prior to the stricture.
The flow and pressure pulsations are damped in the long and dilated collateral vessels that form to

The differential effects of the anatomical variations in coarctation of aorta

Radio Radial Delay

  • The differential effects of the anatomical variations in coarctation of aorta may be diagnosable at the bedside if you carefully compare the brachial pulses between the two arms.
  • If both the brachial pulses and the carotids are strong with delayed or diminished femoral pulses, it indicate that the coarctation is distal to the left subclavian artery.
  • When the left brachial arterial pulse is weak or diminished compared to the right, it indicate that the coarctation is proximal to the left subclavian artery.
  • If the right subclavian has an anomalous origin from the aorta distal to the coarctation, then the right brachial pulse will be diminished or poor.
What is Sign value

Radiofemoral Delay Pulse

There is limited evidence as to the value of the sign and this can be difficult to elicit. The presence of the systolic murmur that is heard under the left clavicle or under the left scapula caused by turbulent blood flow across the coarctation is said to be more common.
