Carrying Out Mass Immunization Programs

Underdeveloped countries and extremely poor regions, such as Nigeria and Africa, depend on massive vaccination campaigns to protect the population from crippling or deadly preventable diseases. Programs geared to immunize millions involve the efforts of many, many people such as volunteers, medical health practitioners, and nurses, and campaigns must be very carefully organized to prevent failure. There are four major elements involved in setting up and carrying out massive vaccination programs for millions of people.

Organizing massive vaccination campaigns in underdeveloped countries such as Nigeria and Africa can prevent thousands of deaths and the outbreak of crippling diseases. Agencies that put together programs to immunize millions of people, often in mere days, require a clear, solid plan and good communication for success. Past campaigns, both successful and failed, have identified four clear elements for massive immunizations of targeted populations.

While people in developed countries are lucky to have regular vaccinations to be immunized against crippling or deadly diseases, other populations are not so lucky and depend on massive immunization campaigns. Vaccination projects required the cooperation of thousands of people to be effective, and a clear plan for dealing with every phase of the program needs to be covered. Four key elements to a successful mass immunization program can be identified and are used for each campaign carried out today.

The first stage of mass vaccination campaigns involves planning. Partners, agencies and organizations must work together and be completely supportive of one another if a campaign is to function properly. Communication is extremely important, as is flexibility and being open to new solutions or different ways of doing things. Coordination involves having a firm plan on how to reach populations and budgeting accordingly is crucial. Who will do what is clearly laid out and everyone is aware of their responsibilities.

The second element that needs ample consideration in a massive campaign is the trip a vaccine will take from its birthplace to the individual receiving the life-saving immunization. For the measles vaccine, this journey is commonly referred to as the 'Cold Chain,' as the vaccine must remain cold the whole trip, from laboratory to child's arm. Sufficient supply needs are again covered in this stage of the campaign, and the planning of the transportation route of the vaccine to its vaccination post solidifies clearly.

The logistics of having a vaccine reach an individual also includes creating the demand segment of a supply-and-demand situation. Individuals need to come to the vaccination post to receive immunization, which is not always an easy task. Some groups of population avoid being vaccinated at all costs, hiding out or simply refusing to be immunized. On the other hand, sometimes the vaccination campaign works so well, individuals from outside the targeted area travel to posts to be immunized and coverage reaches statistics of over 100%. The measles vaccine supply needs are often estimated to be 10% over the population of the targeted group.

One difficulty that immunization campaigns struggle with is creating the demand for the vaccine. It is one thing completely to know that someone needs to be immunized, and quite another to get that message across to populations where education is lacking and myths abound. Anti-governmental groups can hinder mass vaccination programs by spreading messages that vaccines kill babies and children, and organizations must work hard to dispel these rumors. The upside to getting information to the people that need it is that, sometimes, immunization campaigns are more than 100% successful, as people desperate for the vaccines travel to posts from outside the targeted area or population.

In countries where education leaves much to be desired and myths and rumors are rife, it can be difficult to create the demand for vaccines, even when workers know that the distribution is necessary and needed. Mothers of young children will refuse to visit vaccination posts if they think vaccines kill their babies or that the medical health practitioners who distribute the vaccine are witch doctors. Some people believe the vaccines unnecessary, claiming the very symptoms of the disease are signs that the sickness is exiting the body, whereas the truth is that the illness is only progressively getting worse. However, once educated and shown proof immunization works to fight sickness and death, the success rates of mass vaccination campaigns often exceed 100%.

Social mobilization is the third element in a successful immunization campaign. Getting word of the impending vaccinations out there to the population isn't always easy, as communication in underdeveloped countries is often by word-of-mouth only. Workers and volunteers spread the word about the importance of immunization and use neutral symbols (such as the Red Cross emblem) to instil trust. Education about the safety of vaccination is important, and those involved in spreading the word do their best to set superstitions, myths and false rumors to rest.

The follow-up of a campaign has a role in its success by gathering statistics and showing people that massive immunization programs do work. Agencies can see how effective the campaign was, and if their efforts reached the desired goal. Problems that occurred during the vaccination efforts and solutions that were implemented can be a learning tool for future campaigns. If a second wave of vaccinations is required, the need will be noticed in the follow-up stage. In countries that lack education and information, that are rife with myths and have sometimes strong opposition from groups who spread false rumors about immunization, it's especially important to prove to the targeted population that their cooperation in vaccination campaigns had positive results and that less people are dying. Future immunization campaigns for different preventable diseases will have an easier time mobilizing the targeted group and getting them to the vaccination posts.

Perhaps the most important phase of a mass vaccination campaign is the follow-up element, where statistics about success rates are collected. Proof that immunization actually works and reduces crippling diseases and death is the very thing that will draw more people to vaccination stations in the future. Knowing that being vaccinated can prevent sickness is of utmost importance to dispelling myths and rumors created by ignorance, lack of education and anti-governmental pressures. Future immunization campaigns learn from the success and failures of past projects, making improvements to key areas.

The last element of mass immunization is the follow-up phase, where organizers and agencies take in the statistical elements of success and failure. Being able to prove beyond a doubt that their humanitarian efforts had clear success in reducing the death rate of preventable diseases is the strongest weapon organizations will gain. The information also goes a long way to laying rumors to rest and dispelling myths that keep mothers from bringing their children to vaccination posts. Having clear proof that immunization keeps people alive and healthy is the key to making sure mass immunization campaigns are successful.
