Useful Activities during Covid-19

Useful Activities during Covid-19

Covid-19 . . . scary? Ahan! What to do? We are stuck in our homes, nothing to do, nothing to enjoy, just eat sleep, watch movies, dramas, and sleep again. This is the normal mindset of people these days. These days are difficult, no doubt, but just give it a thought that will you be hungry? Will your job will be taken from you? Would this covid-19 snatches from you, your living place? Are you be devoid of your relations? Friends? Family? If the answer is a big NO then be thankful to God, Almighty.

                 The situation is different, so must human activities take a new shape! Sharing is not caring nowadays, but Giving is caring, a new motto. There are a number of things that we are able to get our hands and the reason behind all these useful activities will be our betterment, betterment of the society or the community we are living in. Let’s begin with the amazing list of useful activities: Search for the needy people around you. The very obvious signal of identity for them is that they are not beggars. Now how to locate, identify such people? The answer is very simple, just check their behavior, try to look into their eyes, check their dressing, go to the shop where they are habitual of going, see their payment record, you will definitely find some debt on their heads. Try to pay their bills, send them meal, as a token of love and care. These little actions counts nothing on your part, but a truly big for them.

 Be engage in Online Library concept. Gathering is not allowed in physical boundaries and capacities, but having the young generation on board for making our future bright, hoard them for an interactive and fun-learning story telling platform. Your time will become money and love that you will ooze out from them.

DIY session. Look for the old rags, cuttings, shells, beddings, cardboards or whatever you have stored in your home. This is the right time to take out all that lovely trash and recycle it! Do It Yourself is a very productive idea, create new things out of old ones. Try it out, it will amaze you. Trust me!

 Teach yourself a new skill. Human beings love to progress, but sadly in materialistic things, money matters, their interest is doomed in, that is why they are always in a tension, competition and mentally preoccupied! Just stop this routine in these days and break the shackles of stress, come up with something new and interesting: do some mechanical course, learn stitching, sewing, knitting, dress designing, cooking, beading, painting, calligraphy, card making, preparing organizers for your shoes, underwear, jewelry and much more!

Learn a new language. Yes! You can learn any language free of cost and no matter how young or old you are, as far as you are eager to do something, learn something new, doors of opportunities can never be closed! Duo lingo is the very site where you can register yourself for any language course and believe me you will love to learn there!

 Make a kitchen garden. Fruits and vegetables are getting expensive day by day, so why not preparing a fertilizer and edibles at home! Sounds nice? Ok! Don’t throw away the peels of vegetables are fruits, rather collect them in a bucket half full of fertile soil/garden soil and half with these peels, add cow dung as well to get a rich source of ammonia naturally. Crack the see open, sow it in the damp soil and wait for the germination to take place. Onions are easy to grow, by and by go on garlic, red chilies, tomatoes and coriander. You can prepare pesticide naturally at home too. Search for the ideas from books, internet, and gardeners.

Spend time with family. Read a book together, have a tea together, enjoy lunch, dinner, and breakfast together. Togetherness is unity and unity is beauty. This beautiful unity will strengthen your family and add up color in your life too.

I hope, you would have chosen an activity out of these activities. Have Fun!

Vaccine for COVID-19

Vaccine for COVID-19


Many drugs and treatment strategies have been suggested for COVID-19 but they are not 100 percent effective. COVID-19 vaccine is the ultimate solution. A number of vaccines are being produced worldwide while some are in the phase of clinical trials.
Different companies and institutes are working to find the vaccine that has maximum efficacy and minimum side effects. Companies are taking different approaches for making the vaccine.

Nature of vaccines for COVID-19

Vaccines are divided in various types depending on the virus and immune system. At present, the vaccines that are undergoing clinical trial or are in preclinical stage include various types. University of Oxford is recently running trials on a vaccine that is based on non-replicating viral vector. Similarly, a university in Belgium and Pasteur Institute in France are in preclinical phase of testing their replicating viral vector vaccine. An American company” Moderna” is working on an RNA virus vaccine. These viruses have been successful in the past and are efficiently produced. DNA virus vaccines on the other hand, provide long term immunity and are comparatively inexpensive.
Apart from these, COVID-19 vaccines are also being produced by using inactivated form of the corona virus. Several doses of these vaccines are required to gain the immune response. Contrary to this, live attenuated virus vaccines are also being designed. These vaccines will use weakened viruses to produce fast immune response in human body with few doses.

COVID-19 vaccine: Sole treatment for Corona Virus:

Many treatment strategies are being utilized to get rid of the virus but they all have their own limitations. BCG vaccine has been tested against COVID-19 with no satisfactory results. Similarly, hydroxychloroquine has also proven to be ineffective against this virus. Thus, the fate of corona virus depends on the manufacture of COVID-19 vaccine.

CoronaVirus Vaccine Trials

Coronavirus Vaccine Trials

Development of COVID-19 vaccine would be a turning point in this global pandemic situation. Scientists all around the world are working day and night to make vaccine and to find a treatment for this deadly disease. Countries such as China, USA, Japan, UK and Germany are working on multiple projects and some are already in the clinical trial
Ongoing Trials:

Different companies and educational institutes have created the vaccine and are carrying out clinical trials. Some USA based organizations include:

1– Novavax in pre-clinical phase

2- Inovio pharmaceuticals in phase 1

3- Moderna, which is currently in phase 2 trial

Chinese companies CanSino Biologics and Sinovac are both in phase 1 of the clinical trials. The Chinese company Sinopharm is in phase 2 of trials in china and has also offered to carry out trials in Pakistan. Similarly, University of Oxford, UK is very confident about the results of vaccine trials and is in phase 2/3.

Multiple Phases of Clinical Trials:

The first phase concentrates on testing on a small number of people to observe side effects. In the second phase the vaccine is given to hundreds of people. Third phase involves effectivity testing of vaccine on thousands of people. At this point if the vaccine shows no side effects and the regulatory agencies approve, it is ready to be introduced in market. But sometimes a phase 4 is also necessary to check long-term effects.

Expected Launch of COVID-19 Vaccine in Market:

As various companies worldwide are carrying out human trials on COVID-19 vaccine it is expected that a vaccine would be launched in 12-18 months. If clinical trials, that are being carried out at the moment, prove that a vaccine is effective and does not impose serious side effects only then it would be made available by mid or late 2021.
